Radioactive by Kings of Leon Song Info
According to the Radioactive Songfacts, although the song has never been released before, it has long been in the band's repertoire. Bassist Jared Followill told Billboard: "We played it forever. We started playing it around the time right after we wrote [2005's] Aha Shake Heartbreak . It was kind of in between Aha Shake Heartbreak and Because Of The Times , and there was actually a few songs like that that didn't make it. You know, we save songs until we get them right."
