När en vacker tanke blir en sång ("When a beautiful thought becomes a song"), released in May 1971, is the fourth Swedish solo-album by Swedish pop singer and ABBA member Agnetha Fältskog. With the exception of the last track, all songs were composed by Agnetha herself and the album was produced by Björn Ulvaeus."Ich denk' an dich" (see "Geh' Mit Gott" page ) is the german version of "Han lämnar mig för att komma till dig". This last track, "Dröm är dröm, och saga saga" ("A dream is a dream, and a story a story"), is a notable track because it features Anni-Frid Lyngstad, Benny Andersson and Björn Ulvaeus on backing-vocals; one of the first times all future ABBA members can be heard on one recording.
