Az audio stream -- 2

This app gets playlist metadata from a database by calling a restful endpoint in a json format and plays the url from the json object and displays the song details on the top. Users can select playlist by Artist, Album, Genre and make to the corresponding endpoint to get the list and play. By default it gets the whole list and plays randomly. The main activity/interface will be similar to Pandora or Spotify radio with the main body displaying picture of the artist and then changes to ads. It would have play/pause, next, previous and like buttons only. Should display the song length and position. Option for users to add either email or phone number so they can save their preferences like favorite artist, album or genre as their playlist. This preferences should be saved locally(the json object or in other format) and by calling the REST endpoint as well. Music should play in a service even when app is closed. It should also have a simple widget on screen lock to give users a simple controle. the REST service will be provided to you or we can add that to this project for additional payment.
