Thank you very much Xavier. Great! I'm in. 
There was a proposal from you "feature request for Annotator", approximately one and a half years ago. What I'm trying now is not exactly the same but more or less. It is an "extractor" to obtain metadata from MusicBrainz, i.e., given the path/of/a/song, it looks it up in MusicBrainz and finds the track ID.
However it seems that the webService of MusicBrainz is not so "stable", and I always randomly got "Service Temporarily Unavailable". 
For example, I tried the extractor with "Oops, I did it again" once, and got:
