Vs1053b MP3 Shield

I have purchased a MP3 shield frm sparkfun (VS1053b). The board successfully generates a 'Hello' sound when the sample code is burned on my arduino, but I want to interface an SD card and play mp3 files stored in it. I can't figure out what should be done. So pls help me ...

Current code I'm using ---> http://macauadventure.com/robotics/arduino/hello_world_2.pde

I think where it says:

       // You can do something else here, the bus is free...
       // Maybe set the volume or whatever...

That would be the place to read more data from the SD file. You may want two buffers so you can refill one from the file while the other is being played.

There's a similar project at http://kalum.posterous.com/50759184 that is well written-up, that should be helpful.
