The band forgot to tune back their guitars from "live setting" to "studio setting" for the recording of the song. "Swedish Pagans" is the only Sabaton song recorded in a lower key than the usual E tone the band uses for their studio recordings.
The song became a staple and a crowd favorite in the band's live shows due to the chanting.
The band was forced to play the song due to the popular demand during their concerts. Joakim admitted, that Thobbe Englund wanted to play the song live when it wasn't on the setlist, Thobbe would start playing it on his guitar and encouraged the crowd to sing-along so they would have to play it.
Joakim isn't ashamed of writing the song, he doesn't hate it, but it's very very far from his favorites. He admitted that he's tired of it.
Joakim said that he's proud that so many people like "Swedish Pagans" and that people sing along to it and want to hear live a song he wrote.
