here's four songs
i've appreciated this year:

LucianBlomkamp / Trim

this is a collaboration between a young musician from Melbourne, and British rapper Trim. Neither of them have done anything similar before, that I've heard.

Christopher Port - Bump

I'm so proud of Christopher Port, he is an amazing, and exciting musician. this song is outrageous.

Vince Staples - Summertime

Vince Staples is a LA-based Def Jam rapper. He's unique for showing fear and modesty in his music. he's a rare talent.

Asa-Chang & Junray

Asa Chang and Hidehiko Urayama are digital percussionists from Tokyo. In 2006, their work began getting international recognition, from the Wire magazine, and Fabric UK.
