Well if you are really interested in MP3 decoding try and obtain some
source for a linux mp3 decoder (there are a few of them). This should give
you the general algorithms.  I have heard that someone has obtained
(illegally no doubt) the algorithm that Winamp uses and is trying to make
a better linux mp3 player. The Winamp algorithm uses less cpu than the
classic one. BTW: Winamp is a kick ass mp3 player for Windows.

With that said you probably won't be able to stuff all that code into a
PIC. Also MP3 on the fly decoding with Winamp takes ~10% CPU (44KHz,
stereo, 128) on my ppro200 - this kinda rules out the PIC in terms of raw
computational power.

There already exists one (or two). I don't have a URL handy but they were
pretty expensive (>$300) and had something like 16Meg of flash (maybe
more).
