Music industry: forget bands and singers, just focus on the composer + reinterpretations

Music is a performance.
A song sung ten times, even by the same person will lead to 10 different flavors.
Rhythm can also change, instrumental can change, the singer can change.
In the end, one song can be a huge variety of songs.

Album versions of songs are often pretty neutral.
The real interest is when songs are played live or reinterpreted differently.

Music majors could make much more money, creating value with live songs and different albums.

Classical music is a case in point: interprets are dead 200 years ago minimum, but I'm still hunting next great reinterpretations.
Note that in classical music; we care about the composer, not the singer or the band.
It makes the song atemporal
