How to extract stems from any song

If you've made your way here, I'm gonna let you in on a little secret

That's what I used to make my Editors remix albums. You can feed in ANY piece of music (be it live, demo, album track, whatever) and it will spit out a vocal stem, bass stem, drum stem, and a stem with all the other stuff. Not always high quality, but they're still useful if you're creative and know how to do a good mix. 

Protip: Use the site in incognito mode. That way you can get infinite stems without paying (shhhhhh)
