Music thing burns all my 'Male Attention / Wishlist Calories' every time I look at it. It's a perfectly written, splendidly conceived conpendium of everything I've ever wanted to own. Even if I wasn't previously aware that they existed. Ebay Of The Day is particularly useful. And it's full of splendid features like Tiny Music Makers.
If any of my friends or family are reading this and they're ever stuck for birthday present ideas - get me anything from Music Thing.
