13. All Saints
Girl Power pretty much died with the Spice Girls and it seemed to take all of the other girl groups with it. But during the late 90s and early 2000s, your best bet was to be a girl group. All Saints are living proof of that.
They weren’t the best singers, and heck, they weren’t even the most attractive group of girls we’ve ever seen, but something about them seemed to click with the people. However, they did reform in 2013 in order to get on board with a nostalgia tour.
Namely, they were set to open up for the biggest of the 2000s rejects, the Backstreet Boys, in the UK and Ireland. They did do those dates, but no new music or new found popularity resulted from them. Too bad for them.
