Music, like food...

Sometimes when I find a type of meal or snack that I love I will eat it exclusively for weeks, months or even years but then one day I just completely lose the desire to ingest it ever again. I have noticed that I tend to do this with bands as well, most things I listen to i tend to love forever it seems but occasionally I'll be listening to something that I had once loved and listened to every day and think "damn I never want to listen to this again". It's not even that I think something is bad, it's more that I just find it becoming tired, boring, lackluster in my ears and I can't even figure out why. Maybe the ingredients were changed slightly, maybe I am just that fickle or pretentious even.
