Feeling, every time for me, though I must confess that Billie Holiday gives me a headache every time.
An appalling voice, down there with Adele!
Maybe that’s the problem with feelings, they’re usually just so subjective.
Whereas with technique, there’s normally very little to disagree about. Hank Marvin, Jimmy Hendrix and Eric Clapton are all good technicians despite their obvious differences.
You’re often better off with performers that seem to have a good balance of both - the Beatles, Led Zeppelin, Elvis Presley, Judy Garland, Frank Sinatra, Louis Armstrong, the Smiths etc.
