While I'm a proponent of the 80s was the best decade for music argument, the 70s are a very close second. Too much focus on disco, because it's an easy target. But what else? The Eagles. Aerosmith. Led Zeppelin. The Clash. The Ramones. The Sex Pistols. Billy Joel. Bruce Springsteen. Fleetwood Mac. Black Sabbath. Pink Floyd. David Bowie. Queen. Willie Nelson. Dolly Parton. Lorretta Lynn. Waylon Jennings. Rush. AC/DC...the list goes on, and on, and on.
And it wasn't just that they were great acts, they were changing/inventing genres for the better. So yeah, we missed a little on Disco--but Abba was solid, just watch any girl when Dancing Queen comes on, and for real, Killing me Softly and Staying Alive are bangers--but more than made up for it with other amazing music.
