let's talk music

did you ever think about why you like the music you like? well, as i flipped the channels this evening and came across the beginning of Cheers, I started to think about it. why do i like the cheers theme song so much? it's not like i watched cheers as a kid, but for some reason, i really like to sing along to the theme song. and how does cheers fit in with Green Day? I get the connection to Billy Joel, but why do I like such different music? why does anyone like the music they like? i have no idea.
