I agree.
If the boy (who has been charged as an adult and will be tried as an adult) who raped, strangled, and murdered little Maddy had, instead, committed suicide - without harming her in any way, I would find the song relevant. As it is, he's still alive, while little Maddy is tragically dead after being brutalized by someone she trusted and believed was her friend.
IMO, the song isn't even on the bottom of the list of potential evidence that LE has against Maddy's murderer.
It is interesting in that he had it on his ugly vid of hands playing on Sunday. He is a manipulator trying to gain sympathy with his fake suicide crap.
I know nothing about the song, but to others it has meaning because they know it from their own lives. If it was a song I knew, I could never listen to,it again.
And the bin. It is interesting that he chose recycling where she would have been discovered. It is possible with the other kind, she would not have been found.
Did he want her found? Did he think,he pulled off a crime?
Monster!
