Using a FAQ in place of UX is product design failure
That's quite a simplistic statement that doesn't do justice to this matter.
You would have been right if MusicBee was not able to play apple formats out of the box.
But MuscBee does play them out of the box without the need for any additional tweaks or downloads.
So, how are you suggesting that the UX should pop-up some explanation, only for users that use apple formats,
and experience audio issues?
It's a normal expectation that a user that experiences issues (of any kind) performs some forum and/or FAQ searches.
And users that are reporting issues regarding playback of apple formats clearly have failed to do so.
(PS many MusicBee users (such as me) will avoid apple formats like the plague to begin with, but that's a different topic)
