It's perhaps not the cheapest audio solution, but it works, easy to connect, and it can hold 512 tracks on a µSD-card (no SDHC-support though!)
I made a small sample video:

How to use it?
/*
* This sample uses 5 files on the SD-card. They can be found in netmftoolbox\Samples\Visual C#\Sound Module\samples
*/
public static ushort EXTERMINATE = 0;
public static ushort WAAAAAAAAAAAA = 1;
public static ushort YOUMAYNOTLEAVE = 2;
public static ushort TARDIS = 3;
public static ushort SONIC = 4;
public static void Main()
{
// The module is connected to these pins
Somo SoundModule = new Somo(Pins.GPIO_PIN_D0, Pins.GPIO_PIN_D1, Pins.GPIO_PIN_D2);
// Sets the volume fully open
SoundModule.SetVolume(7);
// Plays "Exterminate!"
Debug.Print("EXTERMINATE");
SoundModule.PlayTrack(EXTERMINATE, true);
// Plays the Tardis-sound
Debug.Print("TARDIS");
SoundModule.PlayTrack(TARDIS, true);
// Plays "You may not leave my precence!"
Debug.Print("YOUMAYNOTLEAVE");
SoundModule.PlayTrack(YOUMAYNOTLEAVE, true);
// Plays the sonic screwdriver sound
Debug.Print("SONIC");
SoundModule.PlayTrack(SONIC, true);
// Repeatedly play "Waaaaaaaaa!"
Debug.Print("WAAAAAAAAAAAA (repeated)");
SoundModule.PlayRepeat(WAAAAAAAAAAAA);
// Let this go on infinitely
Thread.Sleep(Timeout.Infinite);
}
