Yep! I've been using it for years and years. Since at least 2003-4. I just used a recovery service to recover a dead hard drive that had all my music on it, so I've just gotten back into it again after many years of not needing a player at all.
46,000 songs, 465 GB... many from the early days of the .mp3 era.
It's such a fun app to use and configure. Everyone has a different setup and their own personal style of GUI etc.
