I found this site: Moises App: The Musician's App | Vocal Remover & much more | Moises App
It's a nice utility that will separate a song into Vocal/Guitar/Bass/Piano or whatever tracks and you can mute any one of those tracks. It nice to play along with any song and hear just your guitar instead of the song's guitar. You can export the audio with the muted tracks. Pretty cool, could be useful for no-guitar CDLC tracks. It has a free trial to check it out.
