Yesterday, I ate an entire box of Little Debbie Turtle Brownies in one sitting, among other foods, and felt terrible afterward. Tonight, I ate an entire pack of Keebler Coconut Dreams cookies (basically like Girl Scout Samoas), also in one sitting, and feel great. Coincidence? I don't know; too many confounding variables. ​ Why, for certain albums, does infinite replays feel as fresh as the first listen, and I learn all the lyrics by heart, whereas for other albums, all the songs blend together, make me bored, and fade almost instantly from my memory? ​ It's not about style or year of release. What explains it?
