Smart playlist pulls from the same albums over and over

[willduan]

Hi, I have smart playlists set up to group genres together for the purpose of shuffle play. The issue is that multiple songs from the same album appear and when you refresh the list, the same albums show up again. It adds all songs from an album to each playlist and also chooses the same albums repeatedly, which negates my intention of sampling across my library. This pattern happens across multiple genre based lists. Any ideas on how to get it to pull from a wider set of songs? I've tried limiting number of songs, setting the number to 300, playing with sort order to no avail.

Example smart playlist attributes:
Name: Old School
Match: Any
Genre contains Rockabilly
Genre contains Roots Rock
Genre contains Rockabilly
