In essence I agree totally with what you have said here, but it also made me think did every artist want a pop hit ?
I wonder whether some artists who only ever recorded Blues songs did want a pop hit ? they would certainly have wanted the money and fame that would generate, but is that what they were thinking when they recorded their song, or were they just thinking 'I have this great song, about the pain of my breakup with my woman' I want other people to hear it.
Artists who only ever recorded Blues were by the very nature of the music, somewhat world weary, they would have realised that their songs were never going to make it to the top of the 'bubblegum' pop charts, so wouldn't have made songs with that as their aim.
Perhaps they would all have aspired to reach the fame that B B King eventually managed, but did even the mighty B B King have any 'pop' hits ? I honestly don't know.
Just something to think about on a cold, wet, and windy Wednesday morning.
By the way, I'm quite happy to be shot down on this one, but you need to give reasons
