Its funny that I came upon this thread because I'm LITERALLY going through this right now as I type this. Going through my soundcloud like "Yea this needs to be deleted, I hate this". And I spent hours working on these, and got some plays and good feedback and what not, but to me, I don't like them. They could be cleaner. Better, have more depth. But like previous people say, we all eventually go through this. Artists in general, whether its music, painting, dancing, whatever, we all go through hard self criticism.
