My apologies if I'm a slowpoke and you guys have seen this site already, but anyway you type in the song and it gives the bpm

Nice, I checked some known song BPMs on it, and it's right! Except it doesn't do fractional BPMs, it errs to the lower whole number. But it's certainly accurate otherwise!
Do you mean if the song has tempo changes it lists both the tempos,
I would think multiple listings indicate high and low BPMs. So I tested that with tracks I recorded where I know the tempo varies - or that deliberately have at least 2 different tempos - and only got one listing for those entries. So, I don't know for sure what the extra listings indicate.
