I still use it for all of my locally stored MP3s. I haven't seen a music player in a long time that focused on playing music rather than being a media library.
Foobar2K still has an active low key community, it has plugins and a framework that allows tech users to add features and share them, but the main release has the approach I prefer - good display capabilities for media library meta data with flexible layout options .. and it's on the user to populate that meta data with third party tools (or plugins).
Primarily it's just a player, potentially it's a lot.
