Less than two weeks until Grey's Anatomy returns with a new episode, "Where the Wild Things Are," on April 24. For tonight, though, we're stuck with yet another repeat, "The Heart of the Matter," the fourth episode of Season Four.

The Grey's Anatomy episode airs at 8 p.m., and we've got all the action covered in our episode guide, as always. Grey's Anatomy Insider has posted a list of music selections from "The Heart of the Matter," as well as our gallery and quotes.

There's also the Insider staff's entertaining round table from of the episode, and our forum, where you can discuss all things Grey's Anatomy with fellow fans!
