Whatever you think of itunes, it is good for monitoring your music habit (well, when you don't have to reload your library or whatever).
As of today, my highest playcount since 14/12/2010 (when I last had to reload the whole library again) is:
48 Grouper - Heavy water / I'd rather be sleeping
What's yours? And are you surprised.
(Apologies for discriminating against non-itunes users...you have my respect...)
