If you were to think of the 90s, there are a few bands that would come to mind. Spice Girls, Backstreet Boys, *NSYNC, and Aqua. They may not have had quite as many hits as the others, but their songs were truly unique and iconic.
Their hit breakthrough single "Barbie Girl" came out in 1997, almost ten years after the Danish band was originally formed. They finally were able to get worldwide success and grow their fan base to an impressive level.
The band ran into some legal trouble over their mega-hit because the company who made Barbies didn't like the suggestive song. Aqua actually managed to win this case after the judge ruled that there was no issue.
20 years after their first hit song was released the band decided they would reunite. They took part in the "We Love the 90s" music festival that was in both Sweden and Denmark. They had seven concerts where they would perform their old hits that we all used to love.
