We've got a thread for the 80s, but what about the 70s? Lately I've really started to get into 70s music-- lot of diversity and great sounds there.
Bee Gees - Tragedy, Stayin' Alive, How Deep Is Your Love
Carpenters - Rainy Days and Mondays, Superstar, pretty much every song they ever recorded during the 70s
Boston - More Than a Feeling
Carole King - It's Too Late
Michael Jackson - Don't Stop 'Til You Get Enough, Rock with You
Anyone else?
