I have a question about music programs

[Lil' Bitch]

I have a particular song. Is there a music program out there that will let me seperate it so I get an accapella (yeah, I know I butchered the spelling on that one) and an instrumental of it?

Cakewalk might work.

Cool Edit's useful too - although if it's a more popular song you might be able to DL acappellas etc from Kazaa or something...
