You, the ai struggled in smooth vocal parts in the Linkin Park one but it did decent on the Shinoda part and you are a very well trained singer. However, I still hate it because it wasn't as rough in the others for me. I get the impression that it uses one song heavily as a base for these (which could be someone else's arrangement) and the voice is purely from one source. It'll be really cool to see if we get more truly independent ai musicians with training teams though, kinda like a human taking bits and pieces from their favorite bands for some new style except with an actual crew....
