First of all, the only bands you've picked are famous ones. Is that how you judge a band's quality - by record sales? Here would be mine:
60s: 13th Floor Elevators, Bob Dylan, Love, The Byrds, Velvet Underground, Os Mutantes, Nirvana, Hendrix, the Doors, the Incredible String Band, Rolling Stones, Joan Baez, Pearls Before Swine, Pink Floyd
70s: The Stooges/Iggy Pop, Tangerine Dream, Neu, Warren Zevon, Bowie, Grateful Dead, The Who, Francoise Hardy, Marianne Faithfull, Ananda Shankar, Pavlov's Dog, Mahavishnu Orchestra, Frank Zappa, Deuter, Brian Eno
80s: Husker Du, Fugazi, Stone Roses, Skinny Puppy, Einstürzende Neubauten, Queensryche, the Verlaines, The Chills, Bathory, Metallica, Sonic Youth, Nomeansno, Misfits, Scritti Politti, the Associates, Boogie Down Productions, R.E.M, Black Flag, Sodom, Minutemen, Mercyful Fate, Helloween, They Might Be Giants, Pixies, KLF

Stop waiting for a style or scene, discover new bands and develop an individual taste. The 2000s is a little weaker in comparison but there's no musical crisis. We live in this society that reveres the past and bemoans the present and this attitude extends to music.
Besides, loads of bands that we idolise now were virtually ignored in their era, so I'm guessing the same will happen with this decade.

Fair point, but your list does read like a typical NME sort of Beatles/Floyd/U2/Oasis love-in.
