The PS2 version has some slow loading, I believe. I think I remember reading other things that make it inferior.
I own the killer7 2-CD OST (as well as the OST for another game the composer did, called michigan). They're AACs, however, but are 192kbps. I hope the format is all right. I always rip to AAC (.m4a) since I find it to be a better format than MP3.
I'll upload now and see how long it takes, and if it's not all uploaded before I go to bed, then I'll post the links in a few hours hopefully.
Edit: Uploading now, estimated time is 3 hours. :\ I have terrible upload speed.
Edit2: Well, here it is. Uploaded it as one big file... Hope that isn't a problem? When I began uploading I hadn't thought of any kind of limits; just assumed that if it allows me to upload 180.82 MB, that people should be able to download them. Sorry that I didn't split them up into the separate discs if it ends up being a problem.

Also, at some point I removed the composition credits on the ID3 tags. Not sure why. At any rate, tracks 12 and 26 on disc 1, as well as tracks 12, 13, 14, and 16 on disc 2 were composed by Jun Fukuda. However, I believe they are still performed by Masafumi Takada, since the credits also say "All Sounds Directed By Masafumi Takada."
Enjoy enjoy enjoy enjoy enjoy. :)
