Yet another version of Leonard Cohen’s “Hallelujah,” this one sung by Matt Morris and Justin Timberlake on the U.S. Hope for Haiti TV telethon, is now one of the hottest singles on iTunes. This in blatant defiance of Cohen’s request, after countless covers, some of them pretty big hits, that everybody give “Hallelujah” a rest. Given the cause I figure he’ll be okay with the moratorium being broken. (Our Brian D. Johnson probed the lasting allure of “Hallelujah” last year.)
