Reanitheory

Reanitheory is a fan-made Linkin Park album which combines the songs from LP's debut album Hybrid Theory with the remixes of the same songs from Reanimation. All of the songs have somewhat confusing titles, for example, the Crawling/KRWLNG track is called "Raindrops".

This was one of the earlier fan-made efforts, which wasn't able to make use of the many fan-made a capella and instrumental tracks that are on the internet now because they hadn't been created yet at that point. Even so, Reanitheory is very well put-together.

Also, it has awesome cover art that looks as good as a "real" Linkin Park album might look.
