It's the End of the World as We Know It (and I Feel Fine)
"It's the End of the World as We Know It (And I Feel Fine)" is a song by American rock band R.E.M., which appeared on their 1987 album Document, the 1988 compilation Eponymous, and the 2006 compilation And I Feel Fine... The Best of the I.R.S. Years 1982–1987. It was released as a single in November 1987, reaching No. 69 in the US Billboard Hot 100 and later reaching No. 39 on the UK Singles Chart on its re-release in December 1991.
The song originated from a previously unreleased song called "PSA" ("Public Service Announcement"); the two are very similar in melody and tempo. "PSA" was itself later reworked and released as a single in 2003, under the title "Bad Day". In an interview with Guitar World magazine published in November 1996, R.E.M. guitarist Peter Buck agreed that "End of the World" was in the tradition of Bob Dylan's "Subterranean Homesick Blues".
