Slate says pop songs have too many words. I think Joel would agree:

While wordless pop has disappeared from commercial radio, pop music has become ever more long-winded. The year-end top 10 songs from 1960 to 1969 have an average word count of 176. For the 1970s, the figure jumps to 244. In 2007, the average climbed to 436. The top 10 for the week of Feb. 2, 2008, features six songs over the 500-word mark.
