It doesn't really matter to me, as I'm not a Macintosh user anymore, but does it have the smart playlist feature like iTunes?
That's the biggest thing I miss in most music players, including my current one, Google Play Music (with my all-access).
Not sure if you're aware but Simon Weber has a Chrome extension for smart playlists in Google Music.

It's a lean, fast native player that supports tons of formats, has great library management features, and omits all the bloat and confusion of iTunes.
