Music Shield multiple file playback

I would also like to be able to trigger multiple files simultaneously.

I have several mono MP3 files on my SD card; several “background” sounds and other “foreground” sounds.
All my background MP3 files use only the left channel. All my foreground MP3 files use only the right channel.

I would like to be able to play a background mp3 file over the left stereo output. Then occasionally play a foreground mp3 file over the right stereo output while the background mp3 is still playing.

Is this possible?

Maybe you can pre-mix all the combinations of foreground and background sounds into separate files and play those back as needed.
