"Not A Love Song" - Wonderland.
On paper, this girl band formed by Westlife's Kian Egan and Louis "you made that song your own" Walsh should have zoomed up the charts, helped along by a behind the scenes ITV2 series. But if there was proof that you can lead a horse to water, then Wonderland is the perfect example. "Not A Love Song" was their debut single, a nice piece of country-flavoured pop which would probably appeal to Taylor Swift fans for example. But it all went horribly wrong, and their lack of commercial success led to the band being dropped by their record label and ultimately led to a split. They were talented as well as pretty, but their attempt to swim against the current musical tide was their downfall. Right band, wrong time.
