What was the best year(s) for popular music?

I just want years people, so don't go off saying "the 70's" or "the British Invasion" or anything regarding an entire era. Me? I'd say 1980, 1991, and 1967. 1980 had so many #1 hits for rock music, including 'Another One Bites the Dust', 'Another Brick in the Wall', and 'It's Still Rock and Roll to me'. It was also the year that disco went out of style, when Rush released Permanent Waves, and when Iron Maiden began. In 1991, Metallica topped the charts and, with the help of GnR, put hard rock back on top (even though I thought the Black Album wasn't nearly as good as their 80's stuff, it was still pretty good). Nirvana, REM, RHCP, and Pearl Jam (before they started sucking) also had their breakthroughs that year. By 1967, the Rolling Stones and the Beatles were the biggest bands on Earth, the latter of which releasing their biggest album that year, Sgt. Pepper's... This was also the year that Jimi Hendrix and the Doors got big.
