I've been looking for it for a while, but since the soundtrack came out Jan 23 I believe, I dunno if anyone has it yet....
No More Heroes is a game for the Wii directed by Suda 51 in case you were wondering. It's fun (:

they have sample tracks there if you scroll to the bottom of the page

I'm fairly certain there's a link to this within the first few pages of the download links.

I've checked everywhere....literally. But I guess I'll go check again. Thanks (:
