I've added 2 new fields for Albums which are Human "Moods" and Album "Speed".
Hopefully this will give people a nicer way to find music in apps like XBMC.
Mood (happy, sad, high, humorous, in love, relaxed, angry)
Speed (medium, slow, fast, really fast)
Let me know if you want any more added, this was just the ones I could think of for now.
