You may not know this, but iTunes can show you the BPM (beats per minute) of your songs. You can even create smart playlists based upon the BPM. This is helpful when you’re working out and you want a constant rhythm for running or Tai Bo, or if you’re planning a party playlist and don’t want slow songs to bring down the dancing frenzy. But while iTunes can store and display this information, it can’t discern the actual BPMs from your tracks. But Cadence BPM Analyzer Pro can.
