Music Player - play youtube and soundcloud music with background support

We need a simple music player (just the player so no server backend) developed which will have the following feature: The app will have to do the following * Given a youtube and soundcloud link of a track * Play that music in a player * If youtube is selected play youtube music and - show the video in the player like the [login to view URL] app * If soundcloud is selected just play the soundcould music and display the track image * Provide users option of switching sources (soundcloud, youtube) - like [login to view URL] app * The music should be playable in the background when user locks the screen or switches app. For more details PM me. Only serious and experienced developer allowed. Thanks and Happy Bidding!
