I found this neat tool and thought others here might find it useful.
There is a free and open-source tool called spleeter (https://github.com/deezer/spleeter) and it allows you to take any track and isolate the vocals and instruments. I’ve found it pretty useful for stripping away instrumentation on songs where I need the vocals alone.
The code is pretty straightforward and easy to run if you know a little programming Python. I’m not associated with this project at all, but I’d be happy to help anyone who’d like to give this a try.
