I still listen to old favorites like songs by 80's hair bands and old school rap, but other than that, I typically listen to the top Billboard hits. A lot of it has to do with listening to the radio on my way to work, since that's what they play.
Leot55, I agree I still listen to a lot of music from the past. I don't listen to the radio as much as create my own playlists these days, so that takes away from me listening to a lot of billboard music.
