Most iOS 7 users are probably satisfied with accessing music controls in the Control Center. For those looking for more features, Musiex can be installed on jailbroken devices. The tweak works in conjunction with Activator to provide track info and controls from anywhere.
Once installed, an Activator action can be assigned to Musiex, which will bring up a panel at the top of any screen. The panel appears in the same place as incoming notifications, and provides current track information including album art.
Swipe left on the current track and media controls are revealed in the same space. Besides track scrubbing, songs can be repeated or an album shuffled directly from Musiex. When finished using the tweak, swipe up or tap the home button to dismiss.
Settings for Musiex provide options to customize the look of the interface, including Dark, Light, and completely Custom color and opacity options. Musiex works with the stock Music app as well as other media players such as Spotify and Pandora. Note that Musiex is not currently compatible with the iPad.Musiex is available on Cydia from the BigBoss repo for $0.99. Jailbreaking iOS 7.1.x is now possible with Pangu.
