Metro Station were an American pop band, formed in Los Angeles and including Trace Cyrus and Mason Musso, who arrived at the peak of the late-2000s MySpace and electropop era. Their breakthrough, "Shake It", released in 2007 and a hit through 2008, was a bouncy, synth-driven dance-pop song that became a multi-platinum staple of teen radio and ringtones.
The band rode the song to real fame, but internal tensions and the fast-moving pop landscape meant they never landed another single on anything like the same scale. "Shake It" became their calling card and, in commercial terms, very nearly their whole story.
On streaming, "Shake It" sits near 352 million plays, while their next most-streamed track, "Seventeen Forever", trails at around 18 million. That sends the ratio above 19, far past our 5.0 line.
By our measure Metro Station are a certified one-hit wonder. Theirs is a familiar late-2000s pattern: a band that caught a very specific moment in pop perfectly, scored one glossy, hyperactive dance-pop hit that defined a season, then watched the scene move on, leaving that single track far ahead of everything else they put out.
