Shuffle entire collection without Christmas music.

I have had my X12 for a couple of years and found it best to use the genre field to divide up albums. I use the genre to allocate albums between mine, my wife, my daughter and ,Xmas. That way I can shuffle songs (by genre) in album and only get tracks from my own albums ( there you can also shuffle Xmas genre at Xmas) I have the database set up to initially show genre/album and works great for me.
