Kronlund co-wrote Meja's million-selling debut album on Sony and co-wrote two songs for Britney Spears' second album, Oops!... I Did It Again.
From 1999 to 2001, they opened for Britney Spears' "Baby One More Time" U.S. tour and "Oops I Did It Again" European tour, N'Sync's "No Strings Attached" U.S. tour, and were also part of the All That Music and More Festival.
The game contains five songs: "...Baby One More Time", "Oops!... I Did It Again", "Stronger", "Overprotected" and "I'm a Slave 4 U".
Oops not only took its title from the Britney Spears album of the same name, but played around with the title by depicting photos of the aftermath of a murder on the cover art.
On 7 May 2005, Marie appeared on the ITV show, Hit Me, Baby, One More Time, singing "Feels Like I'm in Love" and "Oops!... I Did It Again" in hopes of progressing to the final to compete for the major label release of a new single.
De La Soul sampled "Oops! Here I Go Again" on their song "Pass The Plugs" on their second album De La Soul Is Dead in 1991.
