I admire this approach but honestly it gives me the collywobbles, I'm going to have to lie down.
I'm like Hutchfan, if I like one album by an artist I invariably just have to have more. I have a shelving section specifically for albums that they are the only title by an artist I own, it's quite a small section. This week I bought my first Charlie Mariano and loved it so much I immediately bought another. I'd not even got close to fully absorbing the first.
Duplicates, twice the fun!
