First: Thank you to every single person who contributed in any way. Seriously. And Tom and Steve deserve heaps of praise for the incredible mastering they did in such a short amount of time - truly above and beyond.
The compilation is out!
It's at the Internet Archive (though the vbr MP3 files seem to be taking their time with autoconverting, so I may have to upload them manually this next week) and Bandcamp. Donation page is here.
Go listen and donate (if you can)! And if you encounter any issues, please, please let me know.
