I quite like the three column browser for quickly finding music even if I only have a very fuzzy idea of what I would like right now. It scales quite well, even if you have a library with several thousand songs and a few hundred artists. Together with the hybrid cover view it doesn’t even look very much like a spreadsheet.

Then there’s the grid view which also has its uses. I especially like to display albums by year which gives me a nice chronological overview. Coverflow is pretty worthless, though.

I think that while iTunes gets the big picture somewhat right (at least as far as its audio library functionality is concerned) it gets many details spectacularly wrong. The UI for tagging feels ancient. Oh, and it’s modal. iTunes forces me to play column jockey. I don‘t want to change column widths just so I don’t get vertical scrollbars. iTunes should keep it all nice and tidy for me, kind of like Mail. That, and many other small details.
