first, this is only a comment which might inspire to a healthy discussion. sincerely writing, sonora is eye candy mostly. it's still young, true. it still lacks a lot but just gonna mention that it doesn't read a cover jpg from the music folder, it only relies on online fetching and you can't set a missing cover manually which means that you're gonna get a lot of empty covers if you're not a mainstream music collector. also, a flat hierarchy browser for thousands of artists is pretty limited.
on the other hand, there are also some new refreshing ideas like the queue line and the visual album representation on the search option.
as a sidenote concerning most audio players for mac, i think an application should never "own" the resources. playlists, art, radio stations and the actual audio files, should always belong to the user and remain portable. they should always be read-only, not movable and if an app is kind enough to let us download covers or save playlists, it should not take them away, when we uninstall it. it's a dog-eat-dog competition world where everyone loves to develop its own proprietary library.
first, i thought it was a mac problem, since i came from windows and apps like xmplay, winamp, quintessential player, billy, etc. then i realized it's a change of times. audion, sound app, playerpro and essentially old apps gave much more power to the user. i know the new developers mean well but the truth is you can have both worlds, a minimal ui on top of a powerful feature set.
will keep an eye on sonora. peace everyone.
