Ive been using this app for a few years, and its always been great. My favorite feature is that you can add songs from your own iTunes library to it. I also hope that at some point it will be possible to also add songs from my own playlists (so I can switch from one set of background music to another).
Im happy to see that it was updated so that I can use it on iOS 8. I was also really impressed that I received an email back from the developer within a few hours of requesting that this change be made; he let me know that the update would be ready soon.
