Happened across this by pure happenstance - specifically, saw the heading for thia article (http://www.gameinformer.com/b/news/archive/2011/03/01/magicka-vietnam-is-really-happening.aspx) and just had to see just what was going on in there. A bit of follow-on research, and I discovered that the game's creators have made the soundtrack available for free (http://www.magickagame.com/media/music).

Aww it doesn't look like the soundtrack is available anymore. Anyone willing to share it? =)

Still works for me, you need to download each track individually.

Odd, the page is completely blank with no download links to me. =/
