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.
"(What's So Funny 'Bout) Peace, Love, and Understanding" was written by Nick Lowe in 1974. The original version with his group Brinsley Schwarz was kind of somber, but Elvis Costello made it a classic with his 1978 uptempo take.
"Cruise" climbed from 6-5 on the Hot 100 in its 34th week. In doing so it set a record for the slowest ascent to the Top 5 in the chart's history, which was beaten by Imagine Dragon's "Radioactive" 42-week clamber to #4 three weeks later.
