Default Walkman app

Hi,

I just sold my iPhone 5s and ordered the Xperia Z2 online.

Is the Walkman app able to play the iTunes m4a format and show the artist, song title, album name, artwork etc. I have over 4000 songs in my iTunes library. All my songs are DRM-free.

I would rather not covert these to mp3 as it would result is loss of sound quality.

Thanks
