There are lot of nonsense-lyric songs that I really LIKE, including the aforementioned "Do Wah Diddy" and a whole bunch of New Orleans R&B classics like Jesse Hill's "Ooh Pooh Pa Doo" and Lee Dorsey's "Sittin' here La La (Waitin' for my Ya Ya)." I think that Allen Toussaint may have produced both of these gems ~ he's definitely responsible for the entire Lee Dorsey catalog, and I think he may have done the earlier Jesse Hill record as well.

And then there's Professor Longhair's immortal "Tipitina." Nothing stupid about that, regardless of the absense of any narrative coherence!

Those songs aren't "stupid" ~ they're fun, and they are entirely valid artistic achievements in that they successfully evoke an atmosphere of laughter and good times, making it virtually impossible to remain straightfaced and motionless.

Even those lightweight/airheaded bubblegum songs that Mick dislikes so much are tolerable to me because they aspire to that kind of "feelgood" status (even though they generally fail to reach anyone with halfway-grownup intelligence).

For my money, true songwriting stupidity is most evident where the effort is the most pretentious. And the absolute stupidest song ever to achieve widespread popularity and/or airplay has already been mentioned: "MacArthur Park."
