Turnover 是一款Mac上优秀的音乐BPM分析播放器，BPM（Beats per minute，每分钟拍数）用来测量一首歌曲的速度，如果一首歌的BPM为100，则表示它的速度是每分钟100拍。通过BPM可以简单分别音乐类型。Turnover 就可以帮助我们对整个iTunes音乐库里面的所有音乐文件进行BPM分析，并根据歌曲的BPM为我们创建不同的播放列表，很不错！

TURNOVER… UH, WHAT’S THAT?
An avid runner, the author of this software needed a tool to help build playlists in the 180 BPM range, a cadence, or rate of
turnover, deemed most efficient for running. With thousands of songs to contend with, and existing BPM tappers not quite up to
the challenge, this project was born. So if you’re looking to “improve your turnover”, this is the perfect tool to help you build
the necessary playlists.
