I love the MediaMonkey player, but it bugged me that the beginning of the next track always plays over the end of the last track. This feature is called "crossfading," but it was not clear to me how to adjust it. Here's the path to the crossfading settings...
Tools | Options | Output plug-ins | MediaMonkey DirectSound output | Configure
OR to turn crossfading off entirely, go to the Play menu and uncheck the option Crossfade.
