"Gimme the beat boys and free my soul, I wanna get a-lost in your rock n' roll and drift awaaaaayy..."
Sorry but when I saw the thread title this instantly sprung to mind and I had to say it.
Okay for me, Led Zeppelin, ACDC, Green Day (not sure if this counts as true rock as it's punk rock but I'll say it anyway), Bon Jovi and Queen.
If I had to name a specific song I gotta go with: Stairway to Heaven.
Or Bohemian Rhapsody or Living on a Prayer.
