The Amazon MP3 Store offers downloads of the Nuclear Blast March 2011 Sampler MP3 Album for free. That's the lowest price we could find for this 15-track playlist, released last week. (Several of these songs cost 99 cents on iTunes.) It features various artists from the Nuclear Blast label, including Meshuggah, Sirenia, and Agnostic Front. Amazon MP3 Downloader is required.
