There are a number of software options using AI to break music down into its components. When they work, you can isolate vocals, lead, bass, drums, other components - and also get the rest of the track without whichever of these components you have selected. It’s very clever when it succeeds. It doesn’t always.
It’s also a good way for band members to pick out the detail of the part they will be playing.
