Imagine Dragons' "Radioactive" is the longest-running song in the history of the Billboard charts, and it continues to reach new heights: It has hit diamond status.

The Recording Industry Association of America said Tuesday that "Radioactive" joins Lady Gaga's "Bad Romance," Justin Bieber's "Baby" and Eminem's "Love the Way You Lie" and "Not Afraid" as a digital diamond success. Elton John's "Candle in the Wind/The Way You Look Tonight" is the only physical single to accomplish that feat.

RIAA awards diamond plaques to singles and albums that reach 10x platinum status. That once was the equivalent of selling 10 million songs or albums, but has changed since RIAA began incorporating streaming from YouTube, Spotify and others. "Radioactive" has sold 7.7 million tracks, according to Nielsen SoundScan, and the band's record label, Interscope Records, said the song has been streamed more than 366 million times.

"Radioactive" won a Grammy and spent 87 weeks on Billboard's Hot 100 chart.
