I think everyone is thinking too hard its seriously about selling his soul to the devil for fame

the demon says "please let me free I'll do anything" they came to an agreement the demons freedom for his "name" or fame and fortune and the devil begins to sing through him

the lin about the devil's song not being too long means success was short lived and quickly turns into a nightmare of entrapment into anthony's singing career which is stated by the fact the devil cries all through the night in reference to night after night of being trapped by the devil's song

The end is a reflection that demons arent to be trusted because all the fame he has received still leaves him feeling empty and unfullfilled because he sees the error of his ways and he feels he hasnt progressed because its the devils voice speaking through him rather than his own

I totally love this interpretation.
