I won't say expertise, but what I've done recently:

1) used PixBim AI to extract "stems" (drums, bass, piano, all guitars, vocals). Obviously a lossless source like FLAC works better than MP3 here

2) imported the stems to ProTools.

3) from there, I will usually re-record the bass, guitars, pianos and vocals myself. Occassionally the drums as well.

This is a pretty good way I found to record covers of tracks at home, re-using the original drums if I want to, keeping the tempo of the original track intact etc. I can embellish/replace/modify/simplify parts that I re-record obviously.

It's a bit like drawing using tracing paper, you're creating a copy to the best of your ability, but you have a guide underneath to help you with placement.
