Post-rock: Like the cheesy synthesizers of the 80s, echoing guitar effects on mellow single notes have stained this decade's music. Favorite thing ruined by this trend: The Watchment. Great movie, terrible post-rock score. Damn you Slint.
I really like Post Rock. I was glad to see that they used a post rock soundtrack rather than the typical run of the mill dude tard alpha male butt rock singing some kind of douche ballad soundtrack that gets used in so many comic book movies.
Good Post Rock bands:
The Sea And Cake
The Album Leaf
Thing that I think this decade will be remembered for will be how fat people got. I think people will slowly realize that being fat is not healthy and will eventually start to take better care of themselves.
The skinny girl jeans thing will be laughable.
The return of mid 80's florescent colored clothes.
The Bush Administration (regardless of your views on it)
Pop music invades everything. Hip-Hop is dead as a result. All the Rap stuff on the radio is really just Pop. It was bound to happen to that genre eventually, but just like everything else; they found a formula and have recycled it to death.
R&B bitches over bull**** tracks. Beyonce will not be remembered as this generation's Diana Ross, but more of another stupid bitch from her generation that things more is more. I hate how a lot of R&B bitches through their voice all up and down the scale as if that really sounds nice. Less is more.
