I realize that Dylan is far more accomplished, and obviously there's more to him than that Transformer who won, but at the same time I think that our opinions on the relative merit of song lyrics is biased by our appreciation for the music as well as our appreciation of the message expressed (for some), rather than any underlying aesthetic merit to the "poetry" of the lyrics themselves. I almost want to automatically exclude any songwriters if they would be considered on the basis of their lyrics. Of course, the committee makes such terrible decisions as is that they couldn't ruin things much more these days.
