My tastes have opened up more as I've gotten older. I hated Aerosmith and Black Sabbath when I was a teen. Now that I'm 46, I LOVE them. I also listen to more types of music. I like some of the newer stuff, but not much of it. Since I have a teen that is into Indie music, I don't hear the more mainstream stuff that is played on the radio today so I just don't hear the new stuff. I'm definetly not into today's pop and I don't like rap or hip hop.
Hey, AC/DC just came out with a new album and they play it on the classic rock station I listen too.
But I now will listen to what I call the "old standards" which were my parents music that I HATED when I was younger, however, you will still not find me watching reruns of Lawrence Welk anytime soon.
I also listen to more jazz now too.
Oh and I don't listen to todays country. I like the older country stuff from say before 1985.
And I've found that bands I once listened to a LOT, I don't like so much any more. I used to LOVE, LOVE, LOVE Van Halen. Now, it's just hard to listen to them and I don't know why.
I'm all over the place with music though. Depends on my mood. My ipod has everything from gospel to country to oldies, to standards,rock, blues, jazz, classical and even Scottish Bagpipes.
I literally have something for everyone's taste on there. Even one Black eyed Peas song.
