Writing Playlists

I don't know about you guys, but I make certain playlists I listen to while I write, and I don't know if this is related, but I've experianced writer's block less often while doing this. I make sure there isn't more than one song from a certain artist. I usually go from upbeat, to a softer, slower song, and then back upbeat again. I'll go from hardcore metal rock, to a slow, peaceful song. I make sure that I haven't added any of my current song obessessions, and I love adding songs I haven't listened to in a while. I mix song meanings. The fact that none of the songs have the same theme seems to keep me from going in the wrong direction with whatever I'm writing. Right now mine is:

Edge of the Earth, by 30 Seconds to Mars
Far From the Nuthouse, By Anorexic Beauty Queen
The Fourth Drink Instinct, By Cute is What we Aim For
Jinx, By Green Day
Unwell, By Matchbox Twenty
Nixon, By Merit
The Pornographer's Daughter, By Northstar
Lovers into Ghosts, By The Pink Spiders
Friends Dont Let Friends Dial Drunk, By The Plain White T's
In Fate's Hands, By The Red Jumpsuit Apparatus
Rumors Of My Demise Have Been Greatly Exaggerated, By The Rise Against
Drops of Jupiter, By Train

And of course, I edit it with time. Once you get too used to the order of the songs, it's time to edit the playlist. I don't know if anyone else will find this helpful, but it has made a difference for me.
