i think what kevin devine signifies about him being stoned somewhere and the girl walking by with his shirt and singing his song, thats supposed to show that she doesnt even recognize him as she walks by. though shes obvioulsy a fanatic of his music for randomly humming his song and stuff like that, the fact that she doesnt recognize him and that hes in such a sorry state basically says "youve dwindled down to nothing, and you arent as good as the songs you used to write anymore." thats why the next line says "thats when you're done."
