Sorry to say this, but I don't think there is necessarily a correlation. I think gay guys and str8 guys all listen to a wide variety of music. I'd say see if he wants to hang out and grab food some time. Getting to know him is the best way to figure out if he is gay. Now if you would have said he listens to madonna a lot... well, that's a different story 



















But I actually listen to quite a bit of hip-hop/Rap. I like almost any kind of music though.
Cheesy pop, bring it on! First time in years I listened to Video Killed the Radio Star.
