Jukebox Shuffle - Add Songs window

This window is opened when you click the "Add a song group..." button from the main window. In this window you select a group of songs to be added to the shuffle, and specify how often to play them. You can open this window multiple times, to add multiple song groups to the shuffle.

The same window is also opened when you click the "Edit selected item" button from the main window, but then with the options from the earlier selection already filled in, which you can change as desired.

Songs to be added to the shuffle

At the top of this section there are two radio button options for what songs to add to the shuffle:

The checkbox at the bottom of the section modifies whichever selection you chose above. It filters that selection to include only songs recently added to the Windows Media Player's library, with the maximum age you specify.
Note: this age is the number of days since the song was added to Windows Media Player's database, not necessarily the same as how long they've been on your computer. If you haven't used WMP before, it won't have the songs in its database until the first time it runs and scans the contents of your "Music" folder.

How often (times per cycle) to play songs from the group/playlist selected

The checkbox to "Ignore repeat occurrences of the same song..." means that if any song occurs more than once in your selection (e.g. two playlists that both include the same song), it will only play as often as if it occurred only once (according to the frequency you set for songs with that rating).
