Does what it says it will
I was looking to add BPM information to my tracks so I could create smart playlists based on that information. This application gave me that information. 95% of the time it is accurate. It saves the information to the files and then iTunes Match is subsequently updated. You must have the audio files locally for the analysis but afterwards, you don’t need them. This was exactly what I was looking for and at a price I was happy to pay.
