Amazon: Free 4AD sampler.

Amazon is offering a free 4AD MP3 sampler, featuring artists like Camera Obscura and the National. You have to have their MP3 downloading software, but it's free, works well, and automatically imports to iTunes when it's done.

This is part of the Indie and Alternative Music Sale, which includes lots of other free samplers:

• Dangerbird Records
• Hardly Art 2010 Sampler
• Frenchkiss Records Sampler
• Merge Records Sampler
• Matador Records Sampler
• Saddle Creek 2010 Sampler
• ROIR: So Indie It Hurts Sampler
• Sympathy for the Record Industry Sampler

That ought to make for a decent Memorial Day weekend BBQ playlist, right?
