I am a long time user of CoverScout (I already used v2) and I have to say that I am very happy with this piece of software. My iTunes library does not have one single black image. Even better, the album artwork is stored directly into the music file, and therefore gives much more flexibilty to the handling process.

What I think is extremely neat: the latest integration with equinux' SongGenie. SongGenie finds missing track information and corrects typos.

CoverScout and SongGenie together - never again without both of them.
