I made it in finding the exact release for my first test cd and i am very happy to see that i got results both from discogs and musicbrainz.
with foobar i couldn't find nothing anyhow with both discogs or mbz plugin but i don't think it was because of words.
to get results i had however to change automatic submitted input fields (aside
tracks number which I left unchanged) since they contained accented characters and so on, now, my question is: what are the input criteria for search terms?
