Hey, I am not a big fan of G 'n' R or Iron Maiden- just a slight variance of personal tastes. I lean a bit more toward heavy guitar slightly older classic rock like Led Zeppelin and The Who, but my taste also goes way toward AC/DC, Ozzy, Judas Priest and the like.
I put my music taste aside in the late 80's and stuck with mainstream classic rock (which was called "Rock" then) when I became a young adult JW. So not only did I give up my birthday, I gave up my music.
Boy oh boy, I came back strong to the music. Music is like a drug for me and it always has the right songs to fit the feeling or the general attitude. Older rock tends to be about flipping the bird to mainstream society. I get in moods and music fits right in there.
