eMusic offers downloads of its 29-track eMusic 2011 Pitchfork Music Festival MP3 Sampler for free. That's best deal we could find for this collection of songs. (For comparison, iTunes charges about 99 cents for each track.) It features artists such as Fleet Foxes, Neko Case, Julianna Barwick, Cut Copy, and more.

Of note, Urban Outfitters continues to offer downloads of its 26-track Pitchfork Music Festival Sampler MP3 Album for free. It features different tracks from many of the same artists.
