MsFriz, if this is every night and getting worse instead of better, I'd suggest it's time to find someone to evaluate and treat the anxiety. Cognitive-behavior therapy is really good for this, and he's old enough to do it.
Trying more and more things to fix the situation (music, etc.) just reinforces for him that something big and important is going on, which will make him more wakeful and give the fear more control over him. He needs to learn that going to sleep is no big deal. CBT is the best way I know to re-tool one's thoughts and get them better aligned with reality.
