The musical instrument thing is transitory and depends entirely on the instrument.
Pre-relationship; in a popular band playing a more traditional instrument like guitar with a bunch of also attractive people (or at least part of a cool local scene) = hot
In a relationship and/or solo bedroom producing any kind of electronic music and/or buying lots of synthesizers, drum machines or grooveboxes = not hot
Also note how low “clubbing” is on the least attractive list, so no, DJs and electronic musicians who perform live don’t get a pass
so which country do you hail from?
