Miku Must Die (cover with stock TTS)
So, I use FL Studio and I'm sometimes active on the forums. Every month they have a contest on the forums (unofficial, just for fun) and the winner hosts the next one. I was host and made the theme "Miku at home", which was just "Use the FL Stock Text to speech for most of your song, it could be vocals, or other sounds made out of sampled vocals".
I made a cover of Miku must die, and even the *kick* is TTS. I didn't win or anything, but I thought it was really funny. so 3 years later got the project to open (it crashed 4 times) took a screenshot, and redownloaded the mp3 from the forums. I also have an mp3 of JUST the TTS without any effects, so you can see how much of this is TTS.
