Robot Nein is a song created by 20fadhill. It spoofs the 2005 song "Robot Rock" by electronic music duo Daft Punk, from their album Human After All (track 3).
The song features the original music of "Robot Rock", but the vocals are performed by Downfall Hitler and Inglourious Basterds Hitler, rather than Thomas Bangalter and Guy-Manuel de Homem-Christo of Daft Punk. The opening strings of the song are synchronized with continuous repeats of Himmler stamping.
The video opens with Hitler greeting Himmler and some other Nazis, although it only shows Himmler stamping. After this, it splices alternating scenes of the Robot Rock music video (which shows Guy-Manuel playing a single set of drums and Thomas playing a two-neck guitar) and scenes from Der Untergang.
For the scenes where, in Robot Rock, Daft Punk sing "Rock [guitar riff], Robot Rock! [guitar riff]", it shows Inglorious Basterds Hitler saying "Nein" once (for "Rock!") or three times (for "Robot Rock!"). The distinctive guitar riffs have a scene of Downfall Hitler shouting "Fegelein!" synchronized with them. For the short guitar notes, Hitler just shouts "Feg!"
