I'll bite.
I have several different playlists I use depending on my mood.
Sometimes I watch the last 50 models released on one playlist.
Recently I created a playlist of certain color outfits, i.e. all red, all yellow etc.
Model vs. Model
Themes like the Booster packs, such as Asians, Blondes, Brunettes
Other themes are: Best Asses, Best Tits, Duos
Just mix it up and have fun with it!
