For the benefit of those who’ve joined more recently, I posted a few years back about a site that has catalogued all of the music reviews from a guy called James Hamilton, who was a DJ and record collector writing for a UK magazine called Record Mirror.
His reviews cover 1969 to 1991, featuring BPMs from the late 70s onwards.
He famously went to great lengths to print accurate BPMs for his reviews, including fractions and tempo variations.
