Ace of Base reunited as a trio to perform their first full-length concert since 1996 in Yekaterinburg, Russia, on November 15, 2007.
 They embarked on a world tour called Ace Of Base - Redefined!,
which continued throughout 2008 and 2009.
 The set list included several new versions of their greatest hits.
Jenny confirmed Linn's permanent departure from the group, saying "She hasn't been part of Ace of Base for several years" in Se & Hør Magazine.
Ulf later explained in an interview "She left the band and we promised her to never even ask to come back.
She's done with entertainment industry.
It's understandable.
It’s brutal from the inside, it was not for her.
She has no craving to be famous, she loved her fans, but the fame factor was not for her."
While touring, the group performed a brand new song called "Sparks From A Fire".

The group teamed up with Jenny's husband Jakob to record material for a new studio album, which would consist of seven new songs and seven remakes of old hits.
However, this album did not see a release and a new compilation, Greatest Hits, was released on November 12, 2008, instead.

Five re-recorded songs were released from the album in various forms: "Lucky Love 2009", "Don't Turn Around 2009", "The Sign (Freedom Bunch Mix)" and "Wheel of Fortune 2009", which was released worldwide on October 24, 2008, as a digital single.
A fifth reworking, "Happy Nation 2009", was released separately as a remix kit.
A remake of "All That She Wants" was also recorded and featured guest vocals by Britney Spears that stemmed from her own 2007 cover of the song.
This remake was never officially released, but leaked online in June 2016.

Three of the new tracks recorded in this period ("Sparks From A Fire", "The Mask" and "Wish You Were Mine") were eventually leaked on YouTube in 2017.
