The decoder on the player should play back the files perfectly, except for some known bugs in 2.0 beta 3 where some songs would be played over-clipped and sound like they had static. This is a known bug that was fixed in 2.0beta7. Please do not report or complain about bugs in 2.0beta3.

Either upgrade to 2.0 beta 7 or downgrade to 1.03. After you have done that, see if the problem is still there. If it is still there, please check the file itself by playing it back on the PC. If it sounds good on the PC but bad on the player, please describe in detail exactly what is wrong with the sound and we'll see if we can figure it out.
