I deleted everything. Not just the song, but also the software prototype.
Yes, it was jealousy. Not professional, though. The program wrote better music than me or anybody else did, but that was what I had paid for. What killed me (or rather, it) was that the song it claimed was its best was too long and complex for human perception. It was the best song ever written, it's just that we're all too stupid to understand it.
So I deleted it all, and tried to forget, but I no longer enjoy the songs I used to.
