What am I supposed to listen to?

Listen up to what I'm supposedly supposed to be listening to.  It seems to be that most people expect me to only listen to classic rock and 80's music.  People find out I know some hip-hop and they act all shocked and surprised.  This doesn't really blow my mind, as I myself am not hip-hop.  I'm used to this, but it's happened many times with country music!  What could be more different from hip-hop?  What's hard to believe about me and country music?  I have pretty eclectic taste in music.  Jazz.  Latin.  Broadway.  Whatever.  The list goes on.  I just want to know why people are so often surprised.  It's not a big deal.  Here's the big secret.  I don't like commercials.  If I'm driving and commercials come on, I jump to the next station.  Easy.  It's not rocket science.  How long will I surprise people be listening to different music?  What's more surprising is that more people don't listen to such varied music.  This almost makes me think that other people like commercials more than different music genres.  If I think this through too much I will have to address iPods and such, so I'm just going to wrap this up.
