The Flaming Lips' "Do You Realize??" was named in March 2009 the official Rock Song of Oklahoma. Four years later, Oklahoma's governor Mary Fallin pulled the tune as the state's official rock song in a move her office said had more to do with priorities than musical taste.
"(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.
The Boyz II Men hit "It's So Hard To Say Goodbye To Yesterday" is an a capella cover of a song from 1975 by G.C. Cameron that was used in the movie Cooley High to express the feeling of parting ways with high school friends.
