Hot Butter - Popcorn is considered by Adam and Liam to be the best techno song of all time. It started out in 1971 as one of the earliest synth-pop songs ever. Adam heard it on TV one day and asked his mom what it was. She somehow knew, which was really weird. He then went and downloaded it, and used it in one of his popular home movies which featured the Tasmanian devil rollerblading along to the song.
The actual version of the song Adam heard is a cover by Hot Butter, an alias for keyboardist Stan Free.
