The three The Joshua Tree singles, there were times as a complete set to buy a sticker called the whole thing including as "the seven missing tracks" and basically it was like this: they had enough material to fill an entire LP thus quasi ( others have a Joshua Tree double CD tinkered from the now 18 tracks).
Looking at the single releases from U2, so falls a total of a high proportion of so-called. "B-Sides". Also one way or another live version has been upgraded as a single, ambivalent I see everything falling under "Remix". Also because there were quite nice stuff (unplugged versions of a song, or just something new abgemischtes) once it has been deposited with danceable rhythms ... corresponds to the not quite my taste.
IGCIIDGCT is in its published version on the album in my opinion a terrific song, unfortunate that he has managed just as remix in the setlists. Instead the amount of remix songs I would have rather wished for a "real" B-side or as to the UK "track version of the single, a live track.
I see it like Stefan B. (in another review here): U2 pull as the fans violently the Euros from the nose, which wg. the morbid collective coercion will indeed buy it all.
Maybe it will work with the album in 2010, then there is at least a new material.
