When we first saw this graph of the recording history of Leonard Cohen's "Hallelujah", we thought, a) god almighty everyone needs to stop covering "Hallelujah", and b) everyone really needs to stop graphing songs. It was all worth it though for this Kottke guest-blogger post, which perfectly encapsulates the blinkered triumphalism of the boutique bloggers. You see, a half-dozen random bloggers were all pretty sure that their posts on this graph launched Jeff Buckley's "Hallelujah" cover to number one on iTunes—until their one friend who watches TV pointed out that an American Idol contestant sang it last week.
