Lily Allen wrote "Something's Not Right" for the soundtrack of the Peter Pan prequel, Pan. The song was inspired by the heartache that Allen experienced after suffering a miscarriage when she was six months pregnant with her first child by husband Sam Cooper in 2010.
"Whole Lotta Love" was Led Zeppelin's only US Top 10 hit, charting at #4. Many of their songs, including "Stairway To Heaven," were not released as singles, as it was considered bad form in England to make people pay for singles that were on albums.
The Naughty by Nature hit "O.P.P." doesn't have any curse words, but many oversensitive radio stations played a "clean" version with the word "kitten" edited out, surely the first time that word was censured.
