PyPlay
Music player for touchscreen devices written using Python and QML.
...It runs on Windows and any Linux desktop distribution. Support for Android is planned once PySide is ported to it.
The UI is written using QML, the background is in Python. Playback currently uses Phonon, API, but switch to either Qt Multimedia or GStreamer is planned. After that, video support will be added.
Update: The project is no more avtively developed. I ported it from Python to C++ which allowed me to make an Android version. The new version is called Muzika Player.
