"Don't Bring Me Down" is the ninth and final track on the English rock band the Electric Light Orchestra's 1979 album Discovery.

[8] The song was dedicated to the NASA Skylab space station, which re-entered the Earth's atmosphere and burned up over the Indian Ocean and Western Australia on 11 July 1979.

[8] On 4 November 2007, Lynne was awarded a BMI (Broadcast Music, Inc) Million-Air certificate for "Don't Bring Me Down" for the song having reached two million airplays.

In the liner notes of the ELO compilation Flashback and elsewhere, Lynne has explained that he is singing a made-up word, "Groos", which some have suggested sounds like the German expression "Gruß", meaning "greeting.

"[12][9] Mack stated that this was a temporary line, as "[they] couldn't leave it like that, so eventually we replaced it with 'Gruss,' based on the Bavarian greeting 'Grüß Gott," - 'greet God.'

Thus, it is pretty ironic that the group's biggest American hit, 'Don't Bring Me Down', features no string section at all", adding that "it proved that Electric Light Orchestra could be just as interesting without the string section and thus paved the way for later string-less [sic] hits like 'Hold On Tight' and 'Calling America', concluding that it was a song that was "powerful enough for rock fans but dance-friendly enough for the disco set".

"[17] Record World said that "From the opening drum blasts, through the harmony vocal/percussion break, to the echo-filled closing, this song rocks.

It was released on a compilation album with other re-recorded ELO songs called Mr. Blue Sky: The Very Best of Electric Light Orchestra.
