Split up a long project - how?

I agree., very helpful thread. I think I like your suggestion of keeping all the audio in one place and using left and right markers to work with songs. I’ve gone the route of physically separating songs by deleting all but one song multiple times, but this means if I suddenly get a particularly good snare drum sound, for example, on the eighth song, it’s a hell of a lot of time to go back individually to every song to tweak. With your method, that would be much easier. Thanks for the tip.

Steve.
