steve miller-jet airliner(off book of dreams...its longer)

jefferson starship - we built this city on rock and roll

[Teyety Raetyaert]

also check these out by Zeppelin: The Lemon Song, babe im gonna leave you

[The Answer Is Jesus]

Neil Young - Rocking in the Free World, Harvest Moon :O
Bruce Springsteen - Born in the USA, Born to Run, Streets of Philadelphia

But everything by The Beatles, The Rolling Stones, Led Zeppelin, and Pink Floyd is a good starting point.
