Amazon MP3 Store offers downloads of 13 100 Supreme Classical Masterpieces MP3 Albums from $1.29 each. That beats last week's mention and each is the lowest price we could find by at least $7. Composers in the series include Bach, Brahms, Mozart, and more.

A best bet is the Chopin: 100 Supreme Classical Masterpieces: Rise of the Masters MP3 Album (pictured) for $1.29. That's the lowest price we could find for this DRM-free, 100-track classical album by $7.
