Kings' Followill: 'Radioactive isn't single'

Caleb Followill has confessed that he never planned for 'Radioactive' to become a single.

Speaking to MTV News, the Kings of Leon frontman said that he never felt the track was strong enough to be released on its own.

"I didn't think it would be a single, let alone the first one. I mean, the vocal, I mess up on the first verse, I mess up on the second verse, I mean, my voice is off, so I really didn't think the label would want that as a single, but they wanted it first," he explained.

"I don't know, I think at this point, we could do something with me tapping my foot and singing into a can and [critics] would be like, 'Oh, it's so anthemic', or, 'Oh, it's so stadium-friendly'."

Nathan Followill previously described the song as a "return to gospel".
