REM's "Daysleeper" single, released to promote their 1998 album UP, contains only two songs, "Daysleeper" and "Emphysema."
"Daysleeper" is the familiar song from the album, a tale of corporate angst in which a night watchman loses his sanity as the night defines his existence. It's a nice song, a little different from much of REMs work, but one of the highlights of the album.
"Emphysema" is a quirky instrumental that has a lounge-feel. It definitely sounds like a B-side, and of course is a non-album track.
The material on this single is pretty good, but my complaint is that more was not offered to the U.S. audience. Although there are versions of a "Daysleeper" single with four tracks, they are imports.
By the way, the album UP is worth getting.
