Devoted Grey's Anatomy fans know how big a role music plays on the program. It always succeeds at setting the right mood. It defines the complex characters we love. It gives the terrific writing and acting even more depth. The ambient tracks enhance the emotive power of the show, while introducing audiences to lesser-known and under-appreciated talent.

The Insider has paid tribute to the music of Grey's Anatomy with several special features. Our brief overview of the Original Soundtrack barely scratches the surface. We've compiled a complete song listing of all the music that has been featured on the show, organized by episode, and examined the musical references of the show's episode titles.

All will be updated as new episodes are aired and new information becomes available, and can be accessed by the menu at right. Enjoy!
