Thanks for uploading the Day On The Green bootleg. Regarding whether "No Remorse" and "The Four Horsemen" should be listed as a medley, I think it could go either way. There is a smooth transition between the two songs, so it certainly could be considered a medley. But I think it would be better to list them separately, for these reasons:
 Listing them separately simplifies the song statistics.
 Every other setlist site lists them separately (MetLists, MetPage, ChapterInc, Metallica.com, etc.).
An example of when you would have to list two songs as a medley would be if the band plays (part of) the first song, then (part of) the second song, then part of the first song again. Like Metallica did with "Master Of Puppets" and "Welcome Home (Sanitarium)" in 2000.
yeah, could be a good solution
I left right after Eye for An Eye also, I didn't think they would have a third encore, but they did; my friend stayed and recorded it on video.
I don't know enough about Linkin Park's discography to know if those songs you mentioned should be tagged as @Tape. But, it could be tricky since they have a DJ in the band. Even if the DJ just pushes a button to playback the tape, some people might consider it a performance. But, if the song was played over the PA without any involvement from the DJ, then yeah I'd say it's definitely a @Tape.
Done. It also irks me when people write "cancelled" in the @Info section instead of not posting it in the first place or letting a mod know.
Both videos have the 19th listed as the correct date.
