Music to write by

I spent Saturday night cranking out 4000+ words for a story to submit to Steve Berman's queering Dracula project, listening to Garmarna, a Swedish band that did a lot of interesting music ("God's Musicians" is one of my all time favorite albums). They're one of my go-to bands when I want to focus and get a lot of writing done. I'm also quite fond of Hedningarna, Boiled in Lead, Fiamma Fumana, Blackmore's Night, Steeleye Span, Richard Thompson, (old) Elvis Costello, The Mollys and a few others. Open to recommendations. Who do you really like to listen to?
