Funny, just this morning Soul Coughing's "Super Bon Bon" came on the radio and I thought to myself, "Great senseless song. Now, is that good songwriting?"
And then I came here and found you all wondering the same thing.
It is the music and beat, but I think you get something extra when you get a poem, literature, thrown in as a bonus. The real soul is when the emotion of the music and the story are completely in sync.
But sometimes the whimsy is great too.
