These are the artists who released the best albums of 2007 out of those I've heard so far. I've heard very few - like 100, because I wasn't chasing after trends. Maybe I'll try to catch up at the end of the year, I don't know.
2h company - Zen and the Art of AK-47 Maintenance
Aesop rock - None Shall Pass
Dolphin - Youth
SBPCh - 232,582,657 − 1
Low - Drums And Guns
MIA - Kala
Piano Magic - Part Monster
Psychic Ills - Early Violence
Reuber - Sudpol
Sandra Nasic - The Signal
Serj Tankian - Elect The Dead
A week ago, some funny people accused me that I won't make it into the mega-aesthetic community best_of_2007 with my list. And you can decide for yourselves how poppy it is. As it seems to me, all the featured artists are pretty popular and easy music, there is no avant-garde or heavy stuff here.
This version isn't final, it could very well be that everything will change.
