In a follow-up to the Music post, someone that knows My Gal, asked what bands the goetic spirits like.
As far as background, I noticed they really liked it when a heavy metal song came on the radio and I cranked it up. Actually, it was mostly just one of them but the other joined in as well. You haven't lived until you've watched a demon dance. The first tune I noticed this with was Run for the Hills by Iron Maiden. It is a song about Native Americans running from slaughter. They've also boogied to Judas Priest, Breaking the Law.
I'm not sure if they boogie to the music or how it makes me feel. I know another goetic magician that noticed them boogieing to music as well but that is not my story to tell.
