Aquarium is the debut studio album by Danish-Norwegian band Aqua. The album was released in Scandinavia on 26 March 1997 and in the United States on 9 September 1997. Although the group had been together for three years under their original name Joyspeed, their only release under that name was a single called "Itzy Bitsy Spider". The album is best known for including the successful singles "Barbie Girl", "Doctor Jones" and "Turn Back Time", the first of those being a huge hit across the globe.

Megalomania is the third studio album by Danish-Norwegian pop band Aqua. The album was released physically from September 30, 2011 and digitally on October 3, 2011, more than 11 years after the release of their previous studio album, Aquarius (2000). Due to the change of musical style from their previous album, critical reviews were more mixed, and was not as commercially successful either, only peaking at number two in Denmark, and being certified gold by the International Federation of the Phonographic Industry (IFPI).
