The band claims bootleggers restrict its ability to sing fresh material.
Kings of Leon have slammed people who bootleg their live shows and then distribute the material on the internet.
In an interview with BBC Radio 6 the band claims this kind of behaviour hinders their attempts to play as much new material as possible at gigs and festivals.
Guitarist Matthew Followill told the news provider the group is keen to sing as much fresh material as possible but they know bootleggers will copy them and then post them online.
"You don't wanna play all the new songs live but with technology these days, there'll be someone out there with a recorder and it kinda spoils it for us," he said.
The band's drummer Nathan went on to explain how the band is riding on the crest of a wave and was strong physically, mentally and financially.
Meanwhile, the group recently announced it has added a show at the London Wembley Arena to their upcoming tour.
