I've listened to Pink Floyd 9100ish times in about a year and half. MY POWER... IS OVER NINE THOUSAND!!!
Although I might start afresh, because the second most listened to is Yes, which I haven't listened to in over a year, same as Boston, but both of these are ONLY at 600 listens, but this was in the space of only a couple months last summer.
tl;dr - I spend far too much time listening.
