Maybe it's just that it's what I learned to use first, but for a scattered library of downloaded music across multiple languages, etc., I still haven't found a clearly better solution. It was trivial and fast to find the songs I was looking for, either by filename or by ID3 data, and get them playing.
I suppose that it turns out the world has changed and this isn't how most people consume music anymore, and the writing's been on the wall for a while. But it's incredibly sad to see that model of media consumption finally dying with a whimper. I'm not sure if there are even any modern alternatives for Windows that still optimize for a large library of local music with poor ID3 data quality.
