Matt,
I received the advice from my brother who mentioned the idea after seeing it mentioned in a YouTube video.
I was fairly frustrated with the Audio Chord Wizard. It seemed many of the songs it analyzed would have the tempo doubled, i.e a song with an average 110 BPM tempo would end up with a 220 BPM tempo map.
Since I started following my brother's suggestion, tempo has become a non issue.
I hate it when my little brother is right!
