For me: Spingsteen and Sinatra. I can appreciate their talent, but I just don't feel it Y'know? The irony being: if someone says that about The Beatles I think they're mad.
I don’t really like Springsteen but I do appreciate some of his stuff. I do adore a bit of Sinatra when the mood takes me, what a voice.
I’ve never liked U2 or the archetypal pub singer aka Robbie Williams.
For me it's
Led Zepplin
Elvis
The Beatles (sorry)
Springsteen
Bryan Adams
The rolling stones
Now they do all have the odd one or two songs I like. But not artists I would chose to buy.
