I have found that, often, the tracks, etc. often don't show; but the <Auto-tag by album> routine almost always solves at least the track names, which is the most important task. Having to find and add an album image, or a correct image, is more common. I have only one CD that is not found -without track names: Clark Terry's The Chicago Sessions 1995-96, admittedly not a classic, though a very nice Reference Recordings 2007 issue. Interestingly, it does find the album image. I went into MusicBrainz and did not find it there either/indeed. (I have both MusicBrainz and Gracenote set as tags sources.) One out of hundreds of rips is damn good!
