Sync iTunes Folder between Windows, Linux and OSX machines?

Happy New Year!

Anyone have a solution or a recommendation for syncing an iTunes (Music only) folder between Windows Machine, Linux Machine and a Mac OSX machine?

I have tried Syncthing, but I get an error now when trying to run it and it closes out in windows (go figure). I also tried bit-torrent sync but found that never seemed to sync things up 100%, and then I tried Supersync (even purchased it out right, but turning into a total freakin nightmare!).

Any other recommendations?

Thanks

Are these for different computers? If so Just make the itunes folder shared and everything will sync.

Yes different computers.

Thanks for the suggestion.
