Muxtapes I enjoy

I have been listening to this the most. Favorites: the 3 great Anticon songs in a row (by Why?, Boom Bip & Doseone, and Subtle), the wonderfully exuberant Lonely, Dear track, and the hypnotic, breath-taking folk of Andrew Bird.

Electronic with a moody techno edge. Great picks with a perfectly edible mixtape length. Favorites: Detroit Escalator Company, Boards of Canada, September Collective.

Wildly eclectic. Favorites: The second untitled track, Minnie Riperton/Les Fleur (Flug re-edit).

Sample-based hip hop of the smoked out and heavy on atmospherics vibe. The whole muxtape is well sequenced and well chosen. Favorites: Handsome Boy Modeling School, Mos Def, Klaxons.
