I'm struggling. If I mention any names, it would really be because I don't enjoy the type of music they play. I like MOST music, although I'm heavily influenced by my mood.
The bass playing I like best includes a lot of blues-rock playing, but that's probably because it's the idiom I feel most comfortable with in my own playing - I listen to someone like Leo Lyons (a jazz bassist who ended up majoring in blues rock) and realise with some embarrassment just how hard I try to sound like him...
The fast, jazzy stuff (Jaco's more esoteric stuff, Joe Dart etc.) I struggle with, not so much because I can't play it very well, but because I don't get it musically so I struggle to understand where it's going and that takes away the pleasure in listening and the joy in playing (because if I try it becomes rote repetition if I copy or clichéd patterns if I try and improvise).
I suppose my pet hate is the way straight eighth root notes with a few other passing and grace notes have come to dominate so much popular music - does that mean I should suggest Adam Clayton? The thing I enjoy in 60s and 70s pop music in contrast is that so many songs have creative bass lines that make use of so much more than root-third-fifth-seventh, for me it even makes some 'bubblegum' songs of the sixties worth hearing.
