I've got a particular list of songs I listen to now when I'm writing, but it makes no sense whatsoever, as far as setting a mood. It works for me anyway!
'Feeling of Falling' by Bonnie Raitt
'Beyond Here Lies Nothing by Bob Dylan
'Sway' by Dean Martin
'The Devil Went Down To Georgia' by The Charlie Daniels Band
'Soulful Garage' by Southern Culture on the Skids
'Supernova Goes Pop' by Powerman 5000
'Goo Goo Dolls' by Iris
'The Good Life' by Sammy Davis Jr. (his version is SO much better than Tony Bennett's)
'We Are One' by Kelly Sweet
'Boys Wanna Be Her' by Peaches
'Up Jumps Da Boogie' by Aaliyah/Timbaland/Missy Elliot
That's a few of them. I think I have ADHD when it comes to my music lists.
