Pretty good I might say looking at all the comments here. The rare album I download is rarely on Musicbrainz though, while Discogs[0] always had it.

I'm sure it has something to do with the music genre these albums fall in (hardstyle), but as I said Discogs did have them all and I've heard the same from people with different tastes in music.

So I like to use TagScanner[1] to tag my albums. It searches both MusicBrainz and Discogs and apparently others as well.

P.S. I checked a single artist to see if Musicbrainz has caught up with Discogs yet a few months ago and the only things listed were a 5 year old album and some singles I believe. I just checked again and in the last 3 months some users added everything else.[2]
