As of this moment, Jeff Buckley’s cover of Leonard Cohen’s “Hallelujah”–which Jason Castro performed last night to much fanfare and Googling–is No. 5 on the iTunes Music Store’s Top Songs chart and Nos. 2 and 7 on the Amazon MP3 store’s singles chart; Cohen’s version is also at No. 98 on Amazon. (If the iTunes Store actually charted the digital tracks they’re selling from each contestant, instead of hiding behind a cloak of Fox-sanctioned secrecy, I have no doubt that Castro would be the runaway No. 1 the minute that the contestant’s performances went on sale Friday.) Am I a bad person for being kinda happy that Phil Collins’ “Another Day In Paradise,” which David Archuleta pounded his way through, hasn’t seen a similar bump? [Amazon / iTunes]
