What song is listed as Grey’s Anatomy’s opening theme? The listed opening theme is “Cosy in the Rocket” by Psapp.

“Cosy in the Rocket” is performed by Psapp, the electronic music duo formed by Carim Clasmann and Galia Durant. Its unusual, lightly electronic sound became closely associated with the show’s early title sequence, which juxtaposed hospital preparation with characters getting ready for a night out.

The series did not use the full opening sequence continuously throughout its run. The theme appeared in selected seasons and episodes, while the program often shortened or omitted its title sequence. That history can make viewers remember the instrumental end theme or a silent title card instead.

Other songs listed in the choices—especially “Chasing Cars” and “How to Save a Life”—are strongly associated with memorable Grey’s Anatomy scenes. They are soundtrack songs, however, not the series’ listed opening theme. “Cosy in the Rocket” is the canonical theme credit.
