m-pi.com remixes: There was a folder on his m-pi.com site labeled remixes, there was no clear way to access it but it apparently had quite a few files. Here is the lis, along with the metadata.

~chinchin tunes: On his earlier site that was run on a Japanese file host, he had a page for mp3s you could download. This got infrequent updates.

~chinchin junk project: "hi. hard off here. ...gotta do an album for these mates of mine, and can't be bollocked actually writing any of the tracks.... and anyway, "hard off", is japanese for "second hand junk." email me your worst old trax, and i'll say i made 'em." Track titles are "what other people said about this project."

WFMU: Donna Summer was friends with Hardoff, and played a good couple of songs from him. His song "George's Boy Cunt" would've been track 17 on this Unreleases CD, and he had a CDr named "Blood Is Coming Out Of My Uterus."
