If for you jailbreaking is the great way to liberate your iDevice from manufacture restrictions you should check replace Music app icon tweak on iOS 9. Those users who had jailbroken iOS 7 might used Articon tweak. It was an interesting little jailbreak tweak but unfortunately it hasn't been updated to iOS 9. And here it another tweak called Cairo, an alternative for Articon, that supports iOS 9 - 9.0.2 devices jailbroken with Pangu tool.
The tweak does the only thing, it replaces the now playing app’s icon on the device's Home screen with the album artwork and name with the song’s title. It adds a nice touch to the home screen of your device. The artwork is the same as the one that appears in the Now Playing section of Music when the song is playing.
Once installed, you don't need to do some additional configuration to start work with the tweak. All you need to do is to simply play a song on your jailbroken device and you will notice that the Music app icon will be changed to the current song’s album artwork.
The developer behind the tweak states that Cairo works not only with the Music app but also with all other media apps that have a song playing. This can include Spotify, Pandora etc.
If you want to put some minor changes to the Music app icon and make it more dynamic then Cairo v 1.0 is a great tweak to take for a spin. It is available for $1.49 from Cydia and works perfectly as advertised. The tweak works with iOS 9 or higher devices.
