Roots of Leon Jackson

"Better the Devil You Know" is a song by Australian singer Kylie Minogue, taken from her third studio album Rhythm of Love (1990). The song was written and produced by Stock Aitken Waterman and was released as the album's lead single on 30 April 1990 by PWL and Mushroom Records. "Better the Devil You Know" is known as the song that re-invented Minogue with more sex appeal, as her previous albums were presented with her "girl next door" persona. Her music onwards presented a more independent approach.

"Bleeding Love" is a song recorded by British singer Leona Lewis for her debut studio album, Spirit (2007). It was originally written and recorded by American singer Jesse McCartney, and was co-written and produced by American singer Ryan Tedder. "Bleeding Love" was released worldwide during the last quarter of 2007, and the first of 2008, as the album's lead single internationally, and as the second single in Ireland and the United Kingdom. McCartney later included his version of the song as a bonus track on the international edition of his third studio album, Departure (2008). It is Lewis' biggest hit, to date, and remains her signature song. As of 2021, "Bleeding Love" has been streamed over two billion times.
