it should work okay- there might be a little challenge on this end because all the mp3 conversion software i have likes to add a little extra at the end but i can use trial and error to get the wav file length that will produce the right length mp3. it's actually not difficult. and as long as the music function can go immediately from one file to another with no delay then everything will work beautifully. i think you mentioned that it might pre-buffer the queued files?
