At work, its all about the oldies. Thats basically the only reason why I like work :|
With friends, its Rap/Punk/Electronic music. Also a bit of Metal here and there, but none of the heavy stuff; my friends don't like that stuff :(
At home, its every genre. When I play games or do other stuff, I just open up Windows Media Player and let it scroll through my small music collection. Literally, its quite small.
It browses through a few mega mixes, then some normal trance songs, then some oldies, then some rap, then Goa, then Metal, then some Punk-ish stuff, then it ends with some jazz and other misc. genres.
My parents are also really big into oldies, so the rare times that they listen to music, its old stuff. Like, 60s and 70s stuff.
Lately though, instead of those wannabe "gangsters" riding around listening to Rap, they are starting to listen to Trance and Hardcore a lot more in my town.
It makes me happy inside :)
