Okay, I've made this and it should suffice until someone more experienced than me makes something proper.
It's also only the first verse, because I fail at isolating chrous vocals.
I won't use this for any kind of release myself, but I think it's okay to work with for now.
I just thought I'd share it, someone else could use it too.
