Roon and Owncloud

I have installed a Ubuntu server with Owncloud and Roon. I have created a folder inside Owncloud with some music and then have pointed Roon to read that folder.

All works perfectly. I am a bit surprised, as I thought Owncloud permission wouldn’t permit that.

Do some of you have their own music inside owncloud?

Is it a good practice to put all my music library inside owncloud?
