I'm going to save someone a bunch of typing and just say this, tongue firmly in cheek:
Musicians that know what they are doing are lousy!
You have to be born with talent and "feel", and if you weren't you'll never be a good musician! Being a good musician can't be learned!
Musicians that know theory, can't have good feel, or play anything original!
If you know theory, you just play dorian modes all night, and you can't play any music anyone wants to dance to!
If you know theory, your music is too complicated, you smell bad, and nobody likes you!
(for the record, I agree with what Ric5 is saying, and I like music that grooves.
