I interpreted the “solo” (in quotes!) as a whitewashed self-description for someone prompting a music AI but I don’t think they meant actual solo artists which there are lots of good and impressive ones out there (obviously).

Exactly. In some way this would even be appreciated since I would probably do way more useful and healthy things with the time that I currently spend on YT.

No, only other groups are stupid, but not my group! /s
