Question about Nature UX music player

[MrMLK]

Howdy.

I am in the process from switching from an iPhone to a Note 2. I am asking this question here because I figure their are more people here who might know the answer.

I have a whole bunch of unprotected Audiobooks (m4b). Does anyone know if these can be played in the Nature UX music player? If not, is there another player that might work better?

Thanks.
