What's spiritual to some isn't to others. Lyrics mean different things to different people. Same for any art. You place 15 people in front of a Picasso and your bound to have 15 different meanings.

I went through a period of about 4 months with one song, particularly the melody, in my head. Drove me crazy. Sorry you're dealing with that ugh. Especially since it triggers memories. My only thought is maybe just keep playing music until it stops.
