MusicRandomizer is a music application designed to save the users from the boring task of selecting songs to load to the mp3 player. This tool automatically selects random tracks from the selected directories. It selects randomly from about six different source directories and copies mp3, wav, or wma files to your portable player or hard drive. You can add or delete the files on the player. It also lets you choose the track sources, number of tracks, megabytes or playing time. One of the useful features is its ability to select extra tracks if the source doesn't contain enough tracks to make up required selection.
