Why only this limited range?

Quite surprised I was when I saw that there is the "Rayman Origins" soundtrack but to "Amazon.com" as MP3 download. But the catch: It's only a choice of one of the composer. Billy Martin thus presents his selection of tracks, but what about Christophe Heral?

No question, the items are good, but here you have a tiny handful and the soundtrack includes so many great pieces. The very fact that the "Tricky Treasure" music is not with it, makes the purchase of this "album" doubtful ... The soundtrack there officially for sale (complete course), you have to stop looking for good, perhaps even on other "Amazon's", but this is not worth the money, but the length is about 13 minutes from ... with embarrassing

Conclusion: The music of "Rayman Origins" is one of the best game soundtracks have long and promises many earwigs, but this MP3 album's ridiculous!
