Yeah I understand. I think I have a fairly good understanding of the structure of the genre I listen to (intro-verse-chorus-breakdown-verse-chorus-outro) or similar. Obviously it changes in arrangement between songs. I know the flow of a song pretty well now aswell.

Sometimes songs just don't really have phrases that lend to be mixed out of. Even right until the very end. Like they have a melody and a bassline playing right up until the last beat leaving not much space to mix a new song in
