That's a lot of music and it can't be easy keeping track of it all. Do you have some notes on each to remind you of what you wanted to do? My music writing is very simple where I come up with some words and figure out some chords to go with them. I do not notate it as it would just be me performing the song. Mind you I am looking at getting some friends to play on some in future and I may let them come up with their own parts.
