I'm not saying a musician shouldn't listen to recordings. Obviously they're a very useful tool. But that's all they are - a tool. Like any other special tool it's easy to become dependent, when it really should just be an accessory to your basic set of wrenches. Doesn't matter if you're a mechanic or a bassist - it's a quick fix, a gimmick. Not that it doesn't have a place - just doesn't change what it is.
Of course I don't get as many uber pro gigs as Ken, so feel free to laugh at my comments...
