I have finally found a solution to the problems of a nearly unusable interface, album art issues, and mangled tags. Don’t attempt to use WD Live to play audio files. In fact, don’t use the media library for music files at all. If you wish to see your audio files, you are best off using a media server on the network.
Then, simply use the WD Live as a “renderer” on a phone or computer music player. Since the android remote for the WD Live is more usable than the physical one, it was not a stretch at all to add an android app that will take the music on my network server and play it through the WD Live. On the fly playlists, album art, no tag problems.
