I never said it was apocalyptic. I think a more appropriate phrasing would be that the modern music industry has had a "Dark Age". And I say that very lightly, cause as long as you brush off the surface, you can find good, new music. At the same time, I feel like this decade is going to be remembered as a very.... dry decade, musically. A couple of memorable gems shone through, but for the most part, everyone grew to hate them because the radio abused it once it became popular ("Hey There, Delilah" by Plain White Tees. I can't meet a single person who still listens to it).
I am not a big fan of Hip Hop. It simply doesn't appeal to me. I have somewhat isolated tastes.
My sister made the argument once that once an Indie band is on the charts, they're no longer indie, because it's an explicit contradiction. I can't say I know how I feel about that argument myself, though, cause it neglects to mention that indie is a musical style, and not just a label. Metal does hit the charts, but it's all Nu-Metal, but americans are slowly catching on to the Symphonic metal, like Lacuna Coil, and Within Temptation (and their own Post-Grunge variation of Symphonic Metal, in bands like Evanescence and Flyleaf).
I do understand that there are unique artists, however, they only stay in the spotlight for a short time. I can't say I remember the last time I heard about the Gorillaz, and Amy Winehouse is (rather unfairly) the target of too many jokes for anyone else to take her seriously. (And I actually liked early 90's British alternative. Shoegazing, and such. Makes amazing winter music.)
And I can't say I think one decade was the "best". However, the 90's weren't that bad. They had good Grunge bands like L7, and the 90's were the best decade for gender-equality punk (Riot Grrl, Queercore, and the such). And, of course, the Shoegazing I mentioned earlier.
