Stream Music from KODI library (MariaDB) on Synology NAS to android phone?

Hi,

ist it possible to stream my KODI music library (Synology NAS, MariaDB) to my phone over the internet?
It works fine on my home network, but i’d like to also access it on the go and would prefer my KODI library instead of other solutions, since the music is already scanned and partially rated.
Any advice is greatly appreciated.
