The article discusses the possibility that Daft Punk's song 'Harder, Better, Faster, Stronger' has a tempo of 123.45 BPM, which may be an intentional Easter egg. The author uses their own tempo detection software and manual calculation to determine the song's tempo, finding it to be close to 123.45 BPM. The article also explores the possibility that Daft Punk chose this tempo as a joke, given the song's themes of technology and robotics. The author notes that some of Daft Punk's sequencing software at the time supported fractional BPMs, which could have allowed them to set the tempo to 123.45 BPM.
