Have you ever wanted to remix a track and you just want to grab the vocal? Well, here's two ways of doing that. First, is there's a website called lalal. I think something like that. Anyway, it's linked below.
You can go in there, upload your file and strip out the vocal or strip out the instrumental. If you've got a vocal that's annoying and you want to redo the vocal. Or another way to do it is with iZotope RX where you can upload your file into there. You can go to musical rebalance, solo, the vocal, and there you have it. Just the vocal on its own or flip it the other way and you can have the instrumental on its own.
