Putting the "muse" in "music" - What's your writing jam?

The more I talk to other writers, the more I realize how great a source of inspiration music provides for all of us. Every year during A to Z, many people use their daily posts to share some of their favorite, most nostalgic, most deserving pieces of music, and it is always a treat to browse through those posts. In my own research, I have conversations with people who reveal the many uses music can have in the creative writing process.

Do you do any of these?

Have a playlist for a specific writing project
Do you meticulously assemble a list of songs that are somehow associated with your WIP? Do you often wish that you could publish a soundtrack CD along with your book? Do you have your go-to station on Pandora while you are busy typing away?
(Some writes are better at this last one than others. Some of us require silence when we write - but we still need out music when we are planning!)

Have a playlist for a specific character
Do you have characters in your writing who come with their own mix tape? Do you make lists thinking about what songs your heroes listen to (or would listen to, if they had the time and the means)? Do you come across songs and thing "this is totally Her/Him/Them"! Do your love stories have Their Songs?

Have characters or stories inspired by music
Have you ever listened to a song, staring out the window of a train or jogging away on a treadmill, and though "ooh, this would make a great story!" Have you ever watched a music video, saw a character, and thought to your self "I want to know about that one!" Have you ever been so taken with the mood of a piece of music that you had to put it into words?

Share your music with other writers
Have you ever said the words "YOU GOTTA LISTEN TO THIS!"?

We'll listen! Tell us what your favorite writing music is. Tell us if (and how) music inspires your writing. Tell us about that one nostalgic song that always makes you want to write.
Give us all something to listen to!
