"Deeper Shade of Blue" is a song by British dance-pop group Steps, released as the fourth single from their second studio album, Steptacular (1999), on 3 April 2000. The song was originally recorded by English singer-songwriter Tina Cousins, but aside from a few promotional 12-inch vinyl discs pressed in 1998, her version remains unreleased. "Deeper Shade of Blue" entered the UK Singles Chart at number four and spent one more week in the top 10 before falling down the charts. After a total of nine weeks, it left the top 100.

"Say You'll Be Mine" is a song by British dance-pop group Steps, released as a double A-side with a cover version of Kylie Minogue's "Better the Devil You Know". Steps' cover of "Better the Devil You Know" was later included as the opening track on their third studio album, Buzz (2000), but did not serve as a lead single. A limited-edition single was released as a digipack that was included with a doubled-sided poster in the sleeve. The song is the first to feature all five members on lead vocals.
