…the full backtrack of
http://ccmixter.org/files/P...
cause someone is askin for and
if im readin the rules i’m not allowed!!
I could only upload “samples” n not a whole backing track!!
Is there any “workaround” ???

Although stand alone component tracks are always prefered (and much more likely to be remixed) you can add a single mixed “instrumental” track to your original upload page to that particular song.
This at least gives another mixter the chance to mix another pella or create a new accapella against it.
When you are logged in, and on the page for that particular song, there is a link “manage files” to the left hand side of the page. Follow this link and choose “add a new file”. This gives you a chance to choose “sample” and then give the file a nickname of your choice, say eg “instrumental or “backing track”.
This seems to be tolerated but not prefered. I’m sure theres an admin who can explain this one better than me or an existing thread in the forums explaining mixed tracks.
This song is worthy of the full stems, and you’d be surprised by what others will do with them.
