I've been ripping a few more CDs to my iTunes library in preparation for fully going digital. In the pile I found Insomniac by Green Day, an album I have never, ever, listened to. How did it get there? It was the third CD in a 3-for-2 offer from HMV a few years back. I picked it because I liked American Idiot and the very short running times of the songs made it look like fun.

I bet everyone else has a fair quantity of makeweights in their collection that came from this same sort of scenario.

Also, this has been lost with the advent of digital stores. They don't have the incentives to dispose of back catalog cheaply.
