Add music transfer.

This is a great utility to quickly transfer videos to Android tv! Buddy, you're a genius! 
Could you also add the ability to transfer music (mp3, wav, etc.) and images (jpg, gif, png, etc.)?
This is a cool project, I hope you will develop it, for example it would be nice to release a version for arm64 (for raspberry pi).
Thank you for such an excellent utility.
