This edition included Fredriksson's previously unreleased recording of "Det finns så mycket man inte känner till" ("There Is Much You Do Not Know") as a bonus track,[1] a version of which had originally been released as a single in 1988 by Swedish pop singer Anna Book.

[2] Marie Fredriksson and her then-boyfriend, producer Lars-Göran "Lasse" Lindbom, wrote the majority of songs found on Den sjunde vågen while on vacation in the Canary Islands in the summer of 1985.

[5] Upon release, multiple Swedish journalists commented that Den sjunde vågen was "just another divorce album", as Fredriksson and Lindbom ended their romantic relationship partway through its recording.

[1] The record was promoted by Fredriksson's second solo tour, which began on 28 February 1986 and was initially scheduled to run until 30 April, although it was eventually extended until the end of May due to high ticket sales.

[7] Roxette's debut studio album, Pearls of Passion, was released on 31 October 1986; two days earlier, Den sjunde vågen was issued on CD for the first time, containing b-sides from the two commercial singles as bonus tracks.
