Taylor Swift's “Shake It Off” was inspired by how she'd learned to deal with all the false rumors that circulated about her. "The only thing we can control is our reaction to that ,” said Swift. "You can either let it get to you … [or] you just shake it off."
Kid Rock's "All Summer Long" is a mashup of "Werewolves Of London" and "Sweet Home Alabama." The album it came from was released in October, 2007, but they held off until summer, 2008 for a more seasonable release.
