there is this thing called tempo ambiguity, which basically states that some people may think a song is e.g. 80BPM while others say it's 160BPM.
beaTunes tries to do this justice by posting two numbers. The first is the number that beaTunes thinks is correct. The second is the number that it believes could also be true. If you hover over the BPM value in the main table it shows a tooltip giving percentages of certainty.
