Haha, I am 15 and pretty much in the same boat. Love some of that good music, but I got friends who like it too!
Basically oliveira8's list.
Led Zeppelin, The Who, The Doors, Pink Floyd, The Rolling Stones, The Beatles, Black Sabbath
As well as Steppenwolf, The Guess Who, The Kinks, Eric Clapton (Cream), Santana, Van Morrison, SRV, Booker T & The MGs, SuperTramp, Ray Charles, Queen, Police, Lynyrd Skynyrd, Jimi Hendrix, Janis Joplin, George Thorogood, ETC.
Sorry for such a long list, I thought I should complete a bit of it.
Honestly though, I am sick and tired of all the "gangstas" at school who listen to nothing but rap and a terrible twist on R&B. It seems most of them hate everything that isn't "gangster" and will openly tear stuff like classic rock down.
