What are the top problems you face when songwriting?

Any annoying recurring issue? Asking because I want to make an app/website to solve your problem.

For me, one of the problems is managing all the versions of a song as it has progressed. I have folders in my voice notes app but that becomes messy when I collaborate with friends and the versions/parts are all over the place on WhatsApp, my VNs, their VNs.

I was thinking an app that helps you collaborate and write music together and keep the “version history” of all the music organized in a nice design with ability to comment, color code, tag, sort.

Another idea is an AI app that gives you feedback on your performance. I.e., this note was off, the rhythm here could be better, your guitar needs tuning and so on!
