Just looking at the picture this already seems like amateur work.
As for the music being ... Yes it's pretty flat and unexciting. Realistically lots of today's music is already a remix of a remix and honestly... quite generic.
Bands have been cast for looks for a long time, autotune has been here for ages, and with a better effort in the voice department I don't see AI artists being far off.
I don't think they will ever completely replace artists here, especially since live events really are a thing of their own but.. eh
