Historically, Picture Music was incorrectly identified as Schulze's third album, allegedly preceding Blackdance (1974), based on an erroneous liner note stating it was recorded in 1973.

When preparing a detailed discography in the 1990s, Schulze's biographer and publicity manager Klaus D. Müller researched his personal diaries and discovered that the album did not go to press until early 1975.

[2] Therefore, the official discography was revised again, and Picture Music is now regarded as Schulze's fourth album for both recording and release dates.

Schulze did commission an Amann cover for Picture Music as well (as pictured above, showing a man bound to a ceiling[3]), probably after the first edition of the album was released, but Brain Records did not have a reason to pay the expense of having a new cover designed (unlike his first two albums, which were originally issued under other sub-labels of Metronome Records, Brain's parent company, and then reissued on Brain with new catalogue numbers, so new covers had to be designed anyway), and rejected it.

In 1985, Gramavision Records in the U.S. reissued several titles from Schulze's back catalogue with new covers showing printed circuit boards superimposed over photographs of landscapes (again, an anonymous "in house" design).
