Playing the same song wouldn’t prove anything, because the artist would more than likely do their own rendition.

I disagree because music is always changing and evolving. Rap doesn’t sound like it did during the 80’s, 90’s, and early 2000’s.

When I listen to jazz today (UK artists in particular), they are doing different stuff. Soul/R&B is definitely now than it did 10-20 years ago, which sounds different from the earlier stuff.

You can’t compare Wu, Pac, Guru, Digable, Scarface, Cube, Chuck, Fugess, etc. to anyone today because the music has changed that much. Same with trying to compare Moses Boyd or Makaya McCraven to Tony Williams, or Yazz Ahmed to Lee Morgan, etc.
