A ton of different stuff, changing by my mood or if I feel like singing along or not.
Lately I've been listening to a lot of trap if I don't feel like singing, barbershop music if I do.
My general playlist has anything from edm, to acoustic stuff, acapella, rock, synthpop, etc.
EDIT: I'll add some songs I've been digging lately.
