Requires iOS 7
Also try, Non-Stop Music (iOS 8)
Non Stop Music is a new upcoming tweak that allows Music to continue after respring. It is compatible with the stock Music App, the Spotify App, a the Podcasts App. These applications work flawlessly.
What makes it different?
NonStopMusic plays music as fast as possible. It is built on a custom engine for saving Music Data. If your phone goes into safe mode, NonStopMusic will continue to play music after exiting it. NonStopMusic is also compatible with Spotify. It again uses a special custom engine designed just for Spotify. It also works with Airplay (continues playing in the airplay speaker after respring). NonStopMusic has been in the works for 4 months. We choose to release it now, because we wanted our customers to have the best experience with our Tweak. All bugs have been ironed out. It has a very simplistic settings panel, so the user can easily configure NonStopMusic.
Currently NonStopMusic only works with the Music, Spotify, and Podcasts app. But in a later update, NonStopMusic will be compatible with other music players such as Rdio, Pandora, and SoundCloud. Also the ability to have a specific song play at each respring. More customization with the settings too.
