Radioactive (3:26)

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.”
