Those i dislike quite a lot of popular artists that to me, come under 'Hacks'. So, yes, they have talent and have tapped onto something popular but in my opinion, no sensibility.
I's the difference between a knack for writing or performing catchy product and something genuinely affecting or that says something even if not as memorable. They may be very skilled or original but it leaves me cold.
So Queen, Elton John, Adele, Alicia Keys, Taylor Swift, Ed Sheeran, Pink, Simon and Garfunkel are , to me, hacks. Britney isn't, Madonna isn't, despite being very derivative. Paul McCartney (to some degree) is without the others especially John Lennon. He was balanced out well in the Beatles.
These guys have struck upon very successful formulae but it's strictly business. Eg, I'd argue Patti Smith is. I'd say Harry Styles is a bit of a hack, Yungblud isn't. Donovan was a bit (although I like him), Bert Jansch definitely wasn't.
