There are many un-famous but some very talented artists on youtube doing (playback) covers. Some were kind of nice but until yesterday I never understood the appeal they get

Was listening (more like watching, thinking he must like REM very much ), it hit me the experience is to be listening the same song again but grasping the first impression again . So kind of like listening the same song for the first time 2 times when done with enough self-artist expression these can track a lot of people.

I don't remember the name of the guy, but there was a very famous metal band who recruited a youtuber to fill in the place of one of their guitar players.

All of this wouldn't have been possible if the guy didn't cover dozen of their songs.

In a sense, his covers were his interview with the band

Interesting!
