I remember when iTunes came out for Windows ca. 2003. I had friends with Macs so I leapt at the chance to try it for myself---it just seemed lightyears ahead of whatever I was using to interface with my music library at the time (Winamp, probably). And what a long, slow, weird, decline it's been since then.
Minority here, I never understood why music players shifted towards iTune-ish style of owning and re-categorizing everything in their own way... I mean, OS has a file system, why not just rely on it? Throw some searchable tags in, and you get the same abilities but without obscurity.
I'm not sure what you mean.
