Um.
A) Bob is the man. The Man. Which doesn't necessarily make him right about everything, it just makes him a great lyricist and musician.
B) Wasn't he talking about the
quality of recording? That is what it seems to me. Not the content, the actual sounds that result from modern recording equipment, and the resulting sound of the media it is presented on (CD's).
Anyway, I don't know much about recording, so I'm not sure if he is right about the quality and clarity, and how it sounded so much better in the studio. I would think he would know what he was talking about, having been in studios all his life. But you never know.
If he was talking about musicians, and music, I would agree, with notable exceptions.
But then, my tastes are specific and exacting. I don't throw out a wide musical net. I mean, I do, but then I throw most of the catch back. Because it sucks, and annoys.
