Musical compatibility often outshines personality matching in romantic couples

Sharing a favorite band with a romantic partner might mean more than just having an easy time picking out a concert to attend. A recent study published in Social Psychological and Personality Science suggests that romantic couples share much more similar musical tastes than they do personality traits or personal values. The research indicates that a shared love for specific artists is modestly associated with better relationship quality.

In psychological research, musical preferences refer to the specific genres, styles, and artists that a person habitually enjoys listening to. These preferences are more than just entertainment habits; they act as a reflection of an individual’s psychological makeup, emotional regulation strategies, and personal identity. People routinely use music as a social signal to communicate who they are to others.

Past research indicates that individuals use musical taste to size up potential partners and form initial bonds. For instance, a 2006 study found that music is the most common topic of conversation when young adults get to know each other, functioning as a shortcut to judge someone’s personality. Another study demonstrated that discovering a shared taste in music promotes attraction by signaling similar underlying values.

At the same time, relationship scientists have mapped out how couples match across various psychological traits. A 2023 meta-analysis showed that romantic partners tend to be similar across dozens of behavioral and physical traits. Yet sharing those traits might not actually guarantee happiness. In fact, a 2025 study covered by PsyPost found that actual similarity in personality or personal interests has surprisingly weak and inconsistent links to relationship satisfaction.

Bridging these two areas of research, Julia Vigl and Marcel Zentner of the Music, Emotion, Assessment, and Personality Lab at the University of Innsbruck designed a new project. The researchers wanted to test whether real couples actually share musical tastes to a greater degree than they share personality traits or values. They also sought to determine whether a musical match genuinely predicts how happy a couple is in their relationship.

“We know quite a lot about similarity between romantic partners in personality, values, and other personal characteristics, but much less about similarity in aesthetic preferences,” Zentner, a professor for personality psychology and psychological assessment, told PsyPost. “Music seemed particularly interesting because it is such an important part of how people express themselves and connect with others.”

“Several years ago, I conducted a side-project that suggested an association between similarity in music preferences and relationship satisfaction,” he added. “Julia and I then decided to take up this question again in a more rigorous way.”

To investigate this, the researchers conducted three separate studies involving a total of 309 couples, primarily from Germany and Austria, who independently completed several questionnaires. They rated their preferences for different musical genres and listed their specific favorite and least favorite artists. The researchers used online social tags to categorize these artists, allowing them to measure stylistic overlap even if the partners listed different bands. The participants also filled out standard assessments of their personality traits, personal values, and relationship satisfaction.

To figure out if the couples were more similar than random chance would dictate, the scientists compared the real couples to pseudo-couples. These pseudo-couples were created by randomly pairing up participants from the dataset into artificial relationships. By comparing the real partners to these shuffled pairs, the researchers could measure exactly how much of a couple’s similarity was due to their specific romantic bond rather than just broader cultural trends.

In the first study, which included 99 relatively young couples, the data showed a strong pattern. The real couples were far more alike in their music preferences than the random pairings. This musical overlap was much larger than their similarity in personality traits or personal values. Matching on personality and values had no reliable link to relationship quality, but sharing favorite artists was associated with a modest increase in relationship tenderness.

The second study included 99 couples with a wider age range and longer relationship durations. The researchers used slightly different questionnaires to measure personality and values, but the core findings remained the same. Couples consistently demonstrated higher similarity in their musical preferences than in their personalities. In this older group, the researchers again found a small positive association between sharing favorite artists and feelings of tenderness, though general relationship satisfaction did not show an overall boost.

In the third study, the researchers tested 111 couples and added measures for specific components of love, such as intimacy, passion, and commitment. They also asked the participants about their musical backgrounds, like whether they played an instrument or how much time they spent listening to music. Even when factoring in whether both partners were musicians, the couples still showed an unusually high similarity in their musical tastes. In this group, sharing least favorite artists was linked to a slight increase in feelings of love and relationship satisfaction.

To make sense of the slight variations across the three studies, the researchers pooled the data from all 309 couples into a combined analysis. This broad look confirmed that romantic partners are highly similar in their musical tastes, far exceeding their similarities in personality or values. “Romantic partners tend to have significantly more similar music preferences than would be expected by chance,” Zentner noted. “We were surprised by how consistently the effect emerged across our studies, and by the fact that similarity in music preferences was substantially greater than similarity in personality and values.”

There are a few things to keep in mind when interpreting these results. The association between shared music and relationship happiness is fairly small, meaning that having identical playlists does not guarantee a perfect romance. “The difference between couples and randomly paired individuals was fairly substantial for music preferences,” Zentner said. “The association between music similarity and relationship quality, however, was smaller, so shared musical taste is not what makes or breaks relationships but it seems to help a little.”

The couples who volunteered for the research also tended to be highly satisfied in their relationships. This is a common hurdle in psychological research, as happy couples are more likely to volunteer for relationship studies together. The findings might not fully reflect the dynamics of couples who are experiencing conflict or considering a breakup. “Our studies were correlational, so they cannot tell us whether shared musical preferences contribute to relationship quality, whether partners become more similar over time, or whether similar people are simply more likely to choose one another,” Zentner pointed out.

He also emphasized that the results shouldn’t discourage people whose partners have different favorite bands. “Nor do the findings imply that couples with different musical tastes are incompatible.”

Future studies could look at couples over longer periods of time to see how musical tastes might shift. It is still an open question whether people seek out partners with similar musical preferences from the beginning, or if their tastes slowly merge as they spend years attending concerts together. “We would like to understand how similarity in musical preferences between romantic partners emerges in the first place,” Zentner explained. “Do people generally prefer potential partners who share their music tastes, and are couples already similar at the beginning of a relationship, or do their preferences become more similar over time?”

To unravel these dynamics, the researchers are planning follow-up investigations. “Finally, we will again explore whether sharing music preferences is associated with relationship satisfaction,” Zentner said. “To address these questions, Julia is conducting an online dating experiment and launching an 18-month longitudinal study of early couples this month.”
