Music reaches us in ways that nothing else can. Some great rock songs often have great messages that are quite deep and therapeutic. Here are just a few... 

"I don't need a doctor.
I don't need a pill.
Any other treatment
Babe, would only make me ill. 
I need rock therapy! I need rock therapy! I need rock therapy!
Oh give it to me! Oh give it to me! Oh give it to me!"
—"Rock Therapy" by The Johnny Burnette Rock and Roll Trio, 1956
