Notes: (**) Another reality TV show creation, Girls Aloud were the winners of "Popstars—The Rivals" (UK TV), which pitted a boy band against a girl band, both bands selected by the viewers. As you would expect, "Sound of the Underground" was a big hit. "Stay Another Day" is a cover of a song originally performed by boy band East 17. (HP, 13 Aug 04)
