Q: does it get easier to come up with more stuff over time, as you finish more songs
A: you might get some more wisdom over time, but i feel like nothing is ever going to fully shield you from this dread zone of 'trying too hard' and 'thinking too much.' And i'm not blaming you. The reason you are thinking and trying is because you really care about this damn thing, and rightfully so. But the weird thing about music is it really clams up when people start trying and thinking a lot. It wants to find you, so be aware that it will find you. you just don't always get to decide when. But until then, just recognize all the information you are getting, which, in this case, is that it seems to require a loop. That's actually a very powerful piece of information. it rules out a lot of things
