This is a custom build of the KitKat (Android 4.4) AOSP music app. It should work on most android phones and tablets running Android 2.3 and higher. It's ad free and I have no intentions of changing that There are a couple of modifications: * The notification is clearer and has the album art visible on it * The lockscreen shows the default album art if there's no album art found for a song I'll be changing some other stuff eventually :) Source code from the Android Project found here: http://android.googlesource.com/platform/packages/apps/Music.git Source code of my changes found here https://github.com/rymate1234/AOSP-Music-Plus
