A Change is Gonna Come
For my first entry as me (Mark's let me post as him before), I had to put in a plug for some political involvement this year. After November 2 it'll be all back to the weird stuff, but for right now, the stakes is too high so you need some inspiration. Here are some tracks that do it for me

"Sam Cooke--A Change is Gonna Come" I saw Patti Labelle cover this at the Democratic Convention and was floored. The original is Sam Cooke's zenith. Buy the Album

"Mike Doughty--Move On" I think Doughty's track has got the best synthesis of politics and music this year. Brusie has already posted from this comp put out by Barsuk Records (full disclosure, I work for one of the groups receiving proceeds from this comp)

"Operation Ivy--Unity" This one's to get you worked up. Most recently, this has appeared on the second volume of Fat Mike's Rock Against Bush comp which you can find at Fat Wreck Chords.
