That's a lot!

The song at 13:57 - idea843 sounded amazing, i would love to hear this in full version

I really like the variety in instruments and how they're used. There is plenty of inspiration for me in this mashup. Thxbro!

I wrote up a list of all my favorite ideas, then the browser crashed. :|

Wow, that's a lot of partial songs, I need an army of Erik McClures to complete them all (I need an army of me to do all of the things I want to do as well). All of the fragments sound like the beginnings of something awesome. A literal army of one would be absurdly useful...

One reason you can't finish these is because they are all basically the same idea. I wasn't counting and I didn't listen to the whole thing but a large number are the same exact vi-IV-V progression, and more are some variant of I-IV-V-vi. Come on bro, you're a great musician but you need to push your chord progressions in more interesting ways or you'll just end up stagnating on all your ideas like you are here. (The same thing has happened to me.)

Why not start with some nice jazz chords? Here's a fun progression: Fmaj7-emm7-dmaj7-cmaj7 (mm7 = minor major 7, maj7= major seventh chord).

Other suggestion is you have way too much reverb on your stuff.

It doesn't make a lot of sense for me to qualitatively assess a bunch of tiny ideas, but any of them sound interesting enough to expand into a whole song.
