It took more than four decades, but Black Sabbath have finally earned a No. 1 album on the Billboard 200 chart. Their latest release, 13, sold 155,000 copies last week making it the hard rock veterans' best first-week sales ever, too.

The band made their Billboard 200 debut in 1970 with their self-titled first release. 13 is their 23rd chart appearance, but first with singer Ozzy Osbourne since 1978's Never Say Die! climbed to No. 69. 

Clearly, fans still love the former I Can't Believe It's Not Butter! spokesman.

And if 43 years sounds like an unimaginably long climb to the top for a long-iconic act, well, Sabbath haven't even had it the worst. Tony Bennett, who made his chart debut in 1957 with his fourth album, was a major seller and bonafide star for 54 years before finally reaching No. 1 with his 2011 release Duets II.

Here's to never giving up. Congrats, Black Sabbath!
