I have been looking for a workout selection that I knew would be a consistent beat per minute so I could use it to keep rhythm to and this really works well. There are 105 songs that are up-beat and non-vocal and all of them are labled by the BPM. I created playlists that broke out the songs by: 126 bpm and under 127-129 130-133 134-137 138 and up Each playlist has over 90 minutes worth of music that contains a steady similar rhythm. Ideal for running/walking, eliptical or any other exercise routine that you want to keep a consistant rhythm. In total there is like 8:45 minutes of music, for $7.99. Excelent value for what I was looking for.
