1970 Heavy Metal Hit, Written in 5 Minutes, Was the First by the Band To Place on the Charts

There have been many cases where artists have proven that the record labels know what they’re doing, and the case of “Paranoid” by Black Sabbath is one of them.

The track, which was written in five minutes (or 25 minutes, depending on the band member you ask), was only supposed to be a filler track. Well, the riff itself took five to 25 minutes. The lyrics took a little longer, but it was still a blast compared to other songs. In the end, it became the first track to hit the charts in both the United Kingdom and the United States.

“Paranoid” was included on the second studio album, titled the same name as the track. That has its own story, as Black Sabbath didn’t want the album to go by that name. With hits like “War Pigs” and “Iron Man” on the album, they were sure that one of those would make for a better name. There was also the fact that “War Pigs” would be a little too offensive, especially during that time period!

The record label disagreed. While “Paranoid” may have been quickly put together and added more as filler — because the album was around three minutes too short — the label knew that it would make an excellent hit on the radio. Sure enough, it placed fourth on the UK charts and hit 61 on the Billboard charts in the U.S.

Guitar Worldlooked back on a 2004 interview with bassist Geezer Butler, who explained that after spending two or three days recording the album, he and guitarist Tony Iommi put everything together. “The song ‘Paranoid’ was written as an afterthought. We basically needed a three-minute filler for the album, and Tony came up with the riff. I quickly did the lyrics, and Ozzy was reading them as he was singing.”

However, there was pushback after recording it. Both Butler and Osbourne were concerned it sounded too much like a Led Zeppelin song, and they worried that people would complain.

“Paranoid” has since climbed the charts, even hitting the No. 1 spot in 2025 on the UK Rock and Metal charts. It hit No. 8 on the Billboard Hot Rock & Alternative Songs chart in the U.S. The track would be the final song Black Sabbath would play live with Osbourne still singing live. He died just 17 days after the final performance.
