Not sure exactly what you want this for(but I do like the idea) so I'll just toss out my own method(And there is the rating system, which I don't use, but you might look into). All of my tracks are labelled with .01(IOW, Kick.01, Bass.01, LdVox.01) at the start of any recording. Doing this makes each subsequent playlist automatically name itself, like LdVox.02, LdVox.03, etc. That tells me instantly which take is which. At that point, a pencil and pad allows for quick notes on the fly
