This is really awesome. One thing that I think could be done better would be to display the BPM Deviation by percentage instead of a hard tempo. This is especially important when there is ambiguity over what the tempo actually is. Is this song 90 BPM or 180? That question is pretty hard for a computer to tell, and two great musicians might tell you different answers. It's pretty subjective. Here's an example of two takes of a slow rubato jazz piece. The computer analyzes one using a tempo of 169 BPM and the other at 91. It's the same song, and a very similar tempo. But the one rated faster looks much more erratic because the deviation isn't displayed as a percentage. http://labs.echonest.com/click/?trackId=TRFQMHM123E8585C4A&artist=John+Coltrane&title=06.+Naima http://labs.echonest.com/click/?trackId=TRFQMHM123E8585C4A&#... http://labs.echonest.com/click/?trackId=TRGHGWJ123E858DF63&artist=John+Coltrane&title=09.+Naima+%28alternate%29 http://labs.echonest.com/click/?trackId=TRGHGWJ123E858DF63&#...
