Yes, me. Well, more 'used' than 'use'.
When I first decided/discovered I could rip my huge CD collection to a CD, I stuck a disc in the drive, WMP opened, and I had the choice of many formats, of which WMA Lossless was one.
A few years later I found a lot of unmitigated snobbery, much of which I still don't really understand, but that's for another discussion.
The bottom line is, you get loads of people with PCs, the free media player with most of them is WMP, and the default lossless format is WMA Lossless.
As it turns out, I've only recently started to convert it all to FLAC, but frankly it's not much more than the most minor of pains.
With this update, I needn't have bothered. But on the other hand, it's made me look at my whole folder structure, etc., again and that's actually been more help than harm.
And, let's face it, we all love to tweak...
