The best thing about this app is being able to listen to the same mix at varying tempos. You can listen to your favorite mix at a tempo that matches how fast you feeling like running, biking, etc, that day. Feeling sluggish?Bring the tempo down. Feeling pumped? Speed it up. I really wish we could see the playlist in the app before we download it. Some titles sounded really neat but come to find out its full of songs I hate. Also, what happened to being able to see how a mix is? When Im going for a 45 minute run I dont want to pick a 30 minute mix. Seems to me that when I select a mix at certain tempo and that mix ends and a new mix starts, the tempo chances to the default tempo of the new mix.
