Bjork's unearthly voice swoops and careens, so she makes pop music to match, where you never know whether to expect a techno rhythm or a string section. Like the songs of Iceland's other leading exports, Sigur Ros, her music feels foreign — which not much on this planet does anymore. But thanks to her frequent collaborator Nellee Hooper, her naive, eccentric roundelays are often grounded in solid dance-floor grooves (in England, she even has hit songs). This retrospective compiles fifteen tracks, none from Selmasongs, the soundtrack to the harrowing 2000 film Dancer in the Dark. The best is still "Human Behaviour," her kettledrum-heavy single from 1993. The only disappointment is that Bjork titled a best-of collection something as banal as Greatest Hits. At this rate, she won't even wear a swan to the Oscars anymore.

“Everyday People”

"Everyday People" managed to trailblaze in two different ways -- it was one of the first pop hits to deal with the subject of racial harmony, and it utilized Larry Graham's "slap" technique on the bass guitar, which would soon be copied by countless other bassists. Graham once said about his pulsating style, "I'd never done that before … that's where the freedom of creativity came in for the band, that we'd be allowed to do that." In 1978, the song's line "Different strokes for different folks" would be borrowed for the title of the hit television show Diff'rent Strokes.
