From the same creator who brought us
Snoop Frogg (Kermit sings "Gin & Juice"):
Bodies (Drowning Pool) - Kids' Edition and
King of the Hill's Boomhauer performs (the really fast part of) "Rap God".
As far as I know, in most of the works on their account, the creator performs the vocals themself then uses AI to shift the voice to further impersonate the intended singer, such as what's done with Boomhauer here.

My Elantra is burning oil much faster than usual this month. Arrrrrrgh. I'm hoping the more severe than usual heat is responsible, plus me doing a lot of very short drives on the second day of Go Fest in the middle of severe heat, and thus this won't continue, but I'm also thinking I may have to look for a new used car and see if I can manage to somehow afford one.
