How to sync music folder?

[Odd Rain]

I'd like to copy mp3 files into a folder on my desktop PC, and have them show up on my android phone's music folder (when phone is connected to internet). I don't want to use an USB cable.

Right now I use dropbox but it's not automatic. I put music files into dropbox on my desktop PC. Then, on my phone I have to move them out of dropbox and into the music folder. I want to not have to do the manual moving step.

It doesn't have to be dropbox. Any cloud service is fine.
Any ideas?

If you want to sync your music without USB cable, you can try to use Acer app~ abMusic.

It is very convenient, because you can run on Windows, Android or iOS platform. They have Tutorial video, you’ll know how to use it
