I am a current Clementine user. It is pretty good, but I don't feel it is optimized for collectors with large libraries the way Meelo appears to be. For example, the duplicate finder can't distinguish between the same track that appears on two different albums, e.g. the album it debuted on and a "Greatest Hits" release.

Honest question, why would you want to? What's wrong with having the same song on two different albums in your collection?

Right, it's exactly the opposite of what you're thinking. I want the duplicate finder to NOT report them as duplicates, but it currently does.
