This bpm counter is quite useful for musicians, for dancers, or whoever wants to know the BPM of a song, a sample, or a backing track. This tap BPM tool allows you to calculate the tempo of any song by tapping to the beat. For instance, if you want to know the BPM of a sample or a song, you just have to tap along with the beat.

if you want the BPM of an existing song, i'd recommend Tunebat!

but if you can't find it there, here's an explanation i saw on google:

So when you count how many beats are in one minute of a song played at a specific tempo, you can quickly determine the Beats Per Minute or BPM. And if you're pressed for time, count the beats in 15 seconds of music, and then multiply that number by 4. Voila!
