A free program for android
If you are looking for a customized build of the KitKat (Android 4.4) AOSP in an application, then this is the perfect app for you. The great thing is if you use a mobile phone that runs 2.3 or higher, this would most definitely work on it. In addition to that, you do not have to worry about those annoying pop-up ads because this app is ad-free.
This is a great app to have if you want to listen to your favorite songs and artists. It even notifies you and has all the album covers. Aside from being ad-free, it is also free to download from Google Play Store.
