Input: Question: Who wrote the song that won System of a Down the Grammy for Best Hard Rock Performance? Passage:The second part of the double album, Hypnotize, was released on November 22, 2005. Like Mezmerize, it debuted at No. 1 in the US, making System of a Down, along with The Beatles, Guns N' Roses, and rappers 2Pac and DMX, the only artists to ever have two studio albums debut at No. 1 in the same year. In February 2006, System of a Down won the Grammy for Best Hard Rock Performance for "B.Y.O.B.", beating out other established artists such as Nine Inch Nails and Robert Plant. Their second single off the Hypnotize album, "Lonely Day" was released in March in the United States. System of a Down released "Kill Rock 'N Roll" and "Vicinity of Obscenity" as their next promo singles. The band headlined Ozzfest 2006 in cities where tour founder Ozzy Osbourne opted not to appear or was not playing on the main stage (with the exception of the show at Randall's Island, where Ozzy Osbourne headlined the second stage before System of a Down's performance that night).
