Playback of music files from an external drive attached to a WD TV Live Plus

I just purchased this unit and have discovered a feature of this unit I don’t like and am hoping I am just missing something. I am wanting to playback music from local storage and have the ability to play all files withing any genre listing. What I am seeing is that each time I select a folder from any genre to play (as in wanting to play all the files within that folder), the on screen menu says there is no media in the current. The only way to play any of the music when you have media library enabled, is to select each artists folder and only those songs will all play.

When you have Media library option enabled, the unit automatically sorts the music by genre, artist, album etc. The fact that you cant choose to play all songs within any given category seems quite a shortcoming.

Any feedback would be appreciated.
