BLACK SABBATH'S GEEZER BUTLER approves of T-PAIN's "War Pigs" cover

Last week, rapper-singer T-Pain — who pioneered the use of auto-tune in pop and rap music throughout the late 2000s — released a covers album that aimed to showcase "the power of his natural voice." Alongside renditions of songs by Journey, Sam Cooke and Frank Sinatra, T-Pain also included a soulful, totally un-metal version of Black Sabbath's "War Pigs,"  and Sabbath bassist Geezer Butler thinks it's "great." 

Tweeting out a link to the cover over the weekend, Butler wrote, "Check out T-Pain's great version of #warpigs." The singer probably expected metalheads to bemoan his rendition of the pioneering headbanging staple, so an endorsement from the song's lyricist is about the greatest accolade he could've received. Ozzy, have you heard it yet?
