Having problems removing vocals

Whenever I try the conventional method for removing vocals, it simply won’t work.
I’m trying to remove the vocals from a Ke$ha track, Cannibal. When I found that
didn’t work, I tried TikTok, and that didn’t work either…what’s wrong?

As it explains on the Audacity wiki, Vocal Removal only works if the vocals are panned in the centre of a stereo track.

There’s lots of reasons for Vocal Removal to fail. If the original music is mono instead of stereo, they will all fail.
