Cross platform music player application

I want a Titanium based cross platform (android & iOS) music player application. The application should allow the user to choose a music (audio or video) file from their music library and recorded voice memos and play it. There should be a pause, play, and stop button. The audio should continue to play in the background when the user switches to another application. I don't care what the UI is...just something simple and ugly is fine. Because I don't plan to use your UI...but I want the back end code (e.g. for selecting for selecting a audio/video file from the local device and playing it) to integrate into my application. I am a beginner Titanium developer myself but by offering this job I am trying to speed up my development cycle by not having to figure out which API calls to make etc...
