FR: Use other sources for rich metadata

[gerroon]

Hi

Gonic provides API for Lastfm but that is a closed source privately owned source. It would be nice if Gonic supports MusicBrainz at least for rich metadata for artists and the music.

https://en.wikipedia.org/wiki/Last.fm

Rompr for MPD provides support for MusicBrainz, Wikipedia etc as an example https://github.com/fatg3erman/RompR

thanks
