It depends on what I am doing. If I am working with a spirit as an aid for a working, I will use a song that reminds me of them, such as this for Naamah:
If I am not working with a spirit but have a particular goal I can align a song to, such as a curse, I will play that (for a curse, something like The Animal by disturbed to get me pumped). And then there is Voodoo by Godsmack that I play before ritual just to get me going in general lol
I use the Google play music app and have it set to the evil music radio station. They mostly play dark metal bands but do have some others for variety.
Depend on what I am doing. Year Zero by Ghost is one of my “pregame” songs while preparing for ritual. But during ritual if i do put music on, it’s usually just Dark Ambient like AKLO or something.
I listen to some of peter gundry’s music and viking inspired music from Danheim depending on what shuts my mind down and gets me focused. I listen to Disturbed’s self titled album as well. Only certain songs get me in the zone, others tend to annoy me somehow on a frequency level.
