Black Sabbath rules! All you need to do is look at the album sales charts around the world to see that. And the metal icons just added to their chart accomplishments by topping the Billboard 200 Album Chart in the U.S. as well with their new '13' disc.

The effort sold 155,000 copies in its first week to take the top spot on the Billboard chart, thus solidifying that the group is officially back after a 35 year layoff between albums featuring Ozzy Osbourne as the band's frontman.

Overall, this is Black Sabbath's 23rd entry on the Billboard charts, though not all of them have been with Osbourne. However, despite their lofty pedigree, this marks only the second time the band has scored a Top 10 record. The other was 1971's 'Master of Reality' album. Osbourne, meanwhile, has scored seven Top 10 solo albums over the years, but this marks his first time at No. 1 as well.

"The news is absolutely amazing -- we couldn't have imagined this would happen," said guitarist Tony Iommi. "There have been so many amazing highlights in our long career," added Ozzy Osbourne. "To finally have our first No. 1 album in the U.S. is another incredible milestone for Black Sabbath. Thank you to all of our fans for their support and loyalty." Bassist Geezer Butler concluded, "I'm absolutely stunned. Thank you all worldwide for being the best and most patient fans ever."

While rock is doing well at the cash register, there is some concern as last week's chart-topper -- Queens of the Stone Age's '... Like Clockwork' -- took a major tumble down to No. 15 this week. It's only the third album this year to debut at No. 1 and completely fall out of the Top 10 the following week.

Black Sabbath kicked off their touring support of '13' in New Zealand back in April. The band will continue to promote the disc throughout the year, with North American shows on the horizon this summer. To see their itinerary, click here.
