Altitudes
Stay Frosty
Because it's what normal kids do. If you had friends, you listened to the music. It gave you something to bond over and talk about. Like some 10 year old is gonna know wtf you're talking about if you tell them "Whole Lotta Love" is a good song.
You are very right, because all my closest friends DID listen to Zeppelin and bands similar. Perhaps if I was surround with friends who listen to "Bye, Bye, Bye" by the Backstreet Boys (or 'N Sync? ), I would probably listen to it and share the common bond with them. This can be applied to anything, religion, customs, beliefs, whatever.
I am actually trying to remember the first cd I ever bought. I can't remember to be honest. It might have been Queen.
