The Albums property provides access to the media library, and the Play method plays a song. Consider any current audio playback when using the Play method. If the user currently is playing a different song, the Stop method can be used to stop the current song.

To play a song from a random album in a user's media library

The following demonstrates how to play a song from a randomly picked album (shuffle).

  1. Declare MediaLibrary and Random.

    MediaLibrary sampleMediaLibrary;
Random rand;

  2. Initialize MediaLibrary and the random number generator in the game's constructor.

    sampleMediaLibrary = new MediaLibrary();
rand = new Random();

  3. Stop the current audio playback by calling MediaPlayer.Stop, and then generate a random number that will serve as a valid album index. Next, play the first track in the random album.

    MediaPlayer.Stop(); // stop current audio playback 

// generate a random valid index into Albums
int i = rand.Next(0, sampleMediaLibrary.Albums.Count - 1);

// play the first track from the album
MediaPlayer.Play(sampleMediaLibrary.Albums[i].Songs[0]);
