I'm only asking "typically" because I don't own one and haven't zero'd in on one. But when using an MP3 shield, does the code that plays the file return immediately (by making the hardware player do the work of playing) after it's call or does the arduino have to wait for the return till the mp3 file is played?
I don't know but it would be very bad practice to design these boards so you have to wait for Beethoven's 5th to finish before you could do anything else.

The couple I've seen return immediately and have an IsPlaying function to allow you to find out if a track is being played.

Agreed but I wouldn't have been surprised. I didn't know how much of a role the arduino played in playing the mp3. From the last poster it sounds like the shield does all the work. That's good.
