I do agree that Paul McCartney has had a big influence and that as others have said he doesn't really need anyone to defend himself - he's out there doing it in interviews etc. He plays the music he likes and is very well paid for it, because a lot of people also like that music.
I don't think the question of technique comes into it, and my impression is that the song is always more important in this sort of music. To me though, there's no challenge in this - I suppose it's a whole other debate about "easy listening" and music that challenges you, or is "difficult". This inspires me as a musician, far more than a catchy song. But I suppose the majority of people will always go for the catchy, hummable tune, whereas I like to work out why something sounds the way it does and why it's "different". Maybe I'll start another (off?)topic about what's more "inspiring" - things that are easy to play or that are hard?
