Mumford & Sons have matched a record set by The Beatles in 1964 with a whopping six songs in the Billboard 100.
It follows the tearaway success of their album "Babel" which had sold more than 600,000 copies by Friday - more than any other album this year.
They were helped by having their album on Spotify, where all twelve songs on the album are part of the On-Demand chart which ranks songs based on streams over the week.
The "Glee" cast had previously put nine songs in the top 100, but chart-makers consider them a group rather than a band.
"Number Two was the best we got with [first album] 'Sigh No More' so it would be amazing [to get number one]," said Ted Dwayne from the band (via NME).
"Obviously no-one's going to wish against a Number One record but I know Green Day have an album out and they're a pretty big hitter. If you told me in the '90s that I'd be in a chart battle with Green Day, I probably would have just laughed at you."
