Andrea posted her "summer theme song", which left me thinking what mine could be.
As you see, I have to go with "The Promised Land" by the Boss, courtesy of Jack's summer mix. I don't know that his mix was my favorite of the ones y'all have provided, but I love this song and it seems appropriate to my summer somehow.
[If I picked one from my own mix, it would probably have to be "O You With Your Skirt" by Royal City (BTW, there's a typo in the title of that track on my playlist--it says "shirt")... from Sean's, "Word Iz Life" by Poor Righteous Teachers or "Leaning on You" by the Swingin' Yo-Yo's... from Sam's, "Grounds for Divorce" by Wolf Parade or "Sukie in the Graveyard" by Belle and Sebastian]
Enjoy.
