[Fuze] Preload / Prebuffer Next Track

I will avoid the accursed word in favour of bringing up the issue in this way:

What difficulties might there be in enabling the SanDisk firmware (on the Fuze) to preload or prebuffer the next track to be played (or repeated), to the benefit of audio formats such as FLAC, Ogg Vorbis, or even WAV that add no silence between tracks?

FLAC and WAV are really easy.  Just decode one track and then the next.  Vorbis and MP3 is are a little harder since they add gaps due to how their transforms work.

FWIW all these formats will play gaplessly on your fuze now if you use Rockbox (although Rockbox on the V2 fuze is pretty new and still buggy).
