Tonight, ABC will air a Grey's Anatomy repeat, an episode we saw earlier this fall in "The Heart of the Matter." You can follow the action in our episode guide.

The Insider has posted a list of the episode's music selections (comment or e-mail us if you can find any missing lyrics) as well as a photo gallery and list of the best Grey's Anatomy quotes. Our staff also sounded off in its round table discussion.

As always, you can talk about "The Heart of the Matter," along with all else Grey's Anatomy, in the Insider's FORUM. We welcome all your views and comments!

As we reported last week, the next new Grey's Anatomy episode - and possible strike-induced season finale - is set for two weeks from tonight, January 10.
