Other family members could access it, if your phone died you could still access it, if your phone breaks you can still access it, guests could access it, kids could put on their own movies, everyone can decide what to watch together looking through the choices on the screen, if you lose your phone you can still access it, a long way down the line if the phone app no longer functions or something happens to android/apple it would nice for the tv to be somewhat self sufficient
I'd love this app available on LG and file types like m4a songs should really be able to be played as it's an open source format so free to use . I hear samsung have both these on their tv already...
