Amazon currently has a sale on 99 Essential Chants. Each mp3 is available for 99 cents, but now you can get the entire “album” of 99 mp3 files for less than a buck. I haven’t listened through the whole yet, but you don’t have to like very many to make it worthwhile.
UPDATE: The price has increased to $8.99 for the album. I guess it pays to monitor this blog like a hawk. (Just kidding; don’t bother!)

I’ve now been through the whole thing. Good study music!
Looks like they raised the price since your post, but it’s still not a bad deal ($8.99).
