I think it would be useful to keep "crossfading" and "gapless" playback as distinct concepts. I think they're both useful features, and as judged by the response to this thread, potentially two of the most sought-after additions to the empeg player.

Gapless playback is now a nonissue for the car player, as it can now (in version 2.0) play two tracks back to back with no gap whatsoever.

Any remaining issues with gaps are entirely the result of MP3 encoders and their inherent inability to create truly gapless files due to limitation in the MP3 format. This is all in the FAQ.

So the only remaining thing to discuss is the feature-request for a crossfader (which I will agree is a completely separate and unrelated issue).
