I would love a field that basically rates tracks based on how often they are played, but weighted toward current play rather than older plays. I go through phases of listen to different things, and often use smartlists based on number of plays. Unfortunately, I have tracks with thousands of plays and the ones I am playing a lot currently, don't make it into the SmartList. Here's what I am envisioning:
-It would only need 1 numeric field, called maybe "weighted plays"
-There would be a starting date, say 1/1/1950 and that would be given a value of 1. Every day after that would increase by say .1 (or whatever).
-When you play a track, it would add whatever todays value is to this field. Therefore, more current plays receive more weight and plays in the past are discounted.
-It would be nice if you could set the factor that affects how much more the current plays are favored over older plays.
