Do you think someone's music taste represents there personality?

Yes really.

One such study from the University of Cambridge showed a method of determining how people think and act based on the music they like to listen to. The study targeted over 4,000 listeners, and used a Facebook personality test app to give the participants a set of questions to determine specific personality traits. After a set period of time, the participants yet again received another questionnaire, this time with 15-second song snippets from 50 songs that represented up to 26 different genres of music, to see how they’d react and what kind of music they’d prefer. The results of both tests were then matched to see if there are patterns and correlations to personalities and music preferences.

As it turned out, there were correlations. Mellow music listeners, like R&B and slow jazz, exhibit more empathy, while rock, hip-hop, and house music listeners are more systematic and structural in thought. In addition, people on the more empathic side preferred music with less energy and focus more on negative and heavy emotions like depression, while the systematic side reveled in positive energy and emotions, like happiness and strength.

Basically, people who prefer slower, more smooth music, are more emotional, while people who prefer faster, more energetic music are more logical and structural, according to the study.

I have always wondered this, I think it can differentiate depending on the person.

Pretty much most intelligent people I met who study STEM tend to listen to a lot of mainstream rap and trap music.

Yes really.

Can do but it doesn't for me. I listen to a lot of rock/punk but I don't dress like the stereotypes that follow that (dyed hair, piercings, clothing style or whatever) and I don't act whatever you might associate with that. Just a normal guy who listens to that music.

Sometimes you can look at someone who is heavy on the stereotypes and have a decent idea of what music they listen to but tons of times I've been very surprised at what people listen to.

Someone once told me that the most intelligent people in the world listen to metal/ screamo/ heavy rock music. Either that's not true or I'm one of few exceptions to this principle.
