I was surprised to see that there seems to be no option for batch transfer of music over Bluetooth or related service. It is a pain when one tries to transfer whole albums over Bluetooth. This feature should definitely be included. One should be able to select multiple tracks or even albums and transfer them long press menus for albums should be included for album transfer. Playlists and ques should also be transferable. I'm sorry if this feature already exists and I haven't found it yet. Someone please tell me how to use it if it already exists.
