UPDATE: It appears the original location for BPM Widget is no longer active. I’ve updated the link to an alternate location. Sorry about that.
In this video I demonstrate how the FREE BPM Widget for Mac is used to determine the bpm (beats per minute) of a song. This widget works beautifully with iTunes, since it has the ability to add the bpm to the song with one click. I’ve also provided links to Tap BPM which is a similar tool that works from a web browser, Mac, and PC. Unfortunately Tap BPM does not integrate with iTunes so you will have to add the bpm to the song manually.
