I do, although I use an older version. I used it to play the local music files I've accumulated over the years (I don't always sub for spotify and it doesn't actually have a lot of that stuff anyway).

Even on win10, windows media player is still garbage. iTunes has the column browser which, although disabled by default, is superior for navigation. Its also better for editing file metadata and managing playlists. You can automate iTunes via COM and I have my own command line music player program that uses this, to get playlists and similar metadata.
