This is orders of magnitude cheaper and faster than paying for a song to be created from scratch by a human.

Ouch, yes. One time I commissioned a musician I had befriended to make a piano arrangement of a favorite song to be played at our wedding. The result was great, but it sure wasn't cheap, even if reasonable.

I'd still do this again however, because I really enjoyed the feeling of the community of people contributing our wedding and all the little stories attached. "I prompted ElevenLabs for this!" wouldn't be a memory; a fellow human spending some hours of their life on making this for us and what lead to it is.

There's often value in the provenance of things.
