Last.fm, the UK charts, and the impact of the KLF

Admittedly, what’s more striking is that there seems to be a downward pattern, as if some kind of music was getting slower and slower over the years. There’s also a a strange cluster of tracks around 120 bpm from the early 80s to the early 90s – the big red blob in the middle.

Last.FM spot a pattern in the UK charts… not because it was the default BPM on the Roland-78, but because the KLF told everyone that "120 is the classic BPM for House music and its various variants."
