DefaultPlayer Pro cydia tweak enables you to choose your default music player.
In addition to integrating with the stock Control Center, DefaultPlayer Pro also integrates directly with practically all third-party Cydia extensions, including but not limited to: Activator, Acapella, Auxo, Auxo LE and MiniPlayer.
DefaultPlayer Pro also integrates with most remote control devices, including standard headset controls and bluetooth controls.
In addition to these options, DefaultPlayer Pro also provides the option for launching your designated default player in the background, which may be more ideal for applications that support auto-play/resume upon launch (such as Pandora and TuneIn Radio).
DefaultPlayer Pro also offers additional resume-on-launch functionality for the Spotify and Podcasts apps.
