AVENGED SEVENFOLD singer M. Shadows claims that he isn't bothered by MACHINE HEAD frontman Robb Flynn's criticism of AVENGED SEVENFOLD's new album, telling a radio station in Canada that "everyone should be entitled to say whatever they want." In a lengthy critique of "Hail To The King" at MACHINE HEAD's Facebook page, Flynn wrote that the new AVENGED disc is a "blatant jackery" of material from other acts. Flynn didn't pull any punches, writing, "Congratulations to AVENGED SEVENFOLD on their latest 'covers album' coming in at #1. Who knew that re-recording METALLICA, GUNS N' ROSES, and MEGADETH songs could be such a worldwide hit!!?? Ba-dap Psssssss!!" The singer/guitarist went on to list his "Top 10 jokes about the new AVENGED SEVENFOLD record," starting with Number 10: "AVENGED SEVENFOLD — Now with even MORE METALLICA. " For Number Seven, Flynn wrote, "Eyeliner sales skyrocket as thousands of heartbroken goth girls realize 'Hail To The King' is actually 'that ugly AC/DC band's song 'Thunderstruck'." It was back to METALLICA for Number Three, as Flynn wrote, "'Black album' sales skyrocket as fans realize where new songs came from." And at Number Two, he fired off, "After hearing AVENGED's GUNS N' ROSES cover 'Doing Time', Axl actually calls Slash, says, 'Dude, what the fuck?!'" Flynn maintained that he was just having some fun with AVENGED in his critique, saying he was "happy" for the band's success and adding, "While I like the new record, and really dug the last record 'Nightmare' . . . It's time to poke a little fun at A7X."
