I've been collecting multi-track audio archives in various formats (most ripped from the Rock Band and Guitar Hero style games) and finally curated and organized them into a new file area (accessible to authenticated users only, so you will need an account on Vertrauen, a QWKnet account would work fine):
https://web.synchro.net/files/music/multitrack/
If you were ever interested in hearing isolated instrument or vocal performances of some of your favorite recorded music or you wanted to re-mix a song or overdub/replace your own performance in, these files (questionably legal) are a god-send.
Some songs available as monophonic tracks combined in a single (.mogg) file (importable into Audacity), some separated into stereo pairs (.wav, .mpg, .ogg), or partial mixes (stems) that you can isolate or re-mix with more easily. Many of the songs I have are available in a combination of these formats and with different rates.
If you have some songs that I don't, feel free to contribute (upload, via FTP or X/Y/ZMODEM over terminal) as well.
Enjoy!
