If you noticed, like we did, that every song underscoring last week's episode of Grey's Anatomy was an '80s cover, you picked up on a collaborative effort between Grey's creator Shonda Rhimes and music supervisor Alexandra Patsavas — what they call the '80s Covers Project.

"Shonda had this idea back in the fall, and we started to talk about songs she knew would make sense with the story," Alex recounts to The Hollywood Reporter. (Alex and her company, ChopShop, have also supervised the soundtracks to Private Practice, Gossip Girl, The O.C., The Hunger Games, and Twilight.)

"We started with a couple of songs that she was interested in seeing if there were great modern interpretations for, but at some point along the way, she felt strongly that the way to tell the story in the second half of the season was to use modern interpretations of her favorite songs of the '80s and the songs she felt would tell the story the best."

"I called Alex Patsavas with what I worried was a bad idea: I wanted to see if we could find covers of '80s songs," Shonda explains. "Alex is why I have good taste in music. She creates the pool of music from which I choose songs to go on my shows … Happily, Alex told me she loved the idea. She then asked me to make a list of songs I wanted to hear covered. I went off and wrote down every '80s song that I ever loved, and I made this very long list."

Alex then contacted music labels and publishers and eventually received hundreds of submissions.

"She'd email me these ZIP files with, like, five different artists each covering the same Whitney Houston song, and I would go out of my mind with excitement. It's honestly become the most fun part of my job."

Together, they distilled the collection down to 40 to 50 songs. In the coming weeks, we'll hear an "amazing" version of "Time After Time" by The Wind and the Wave and a "brilliant" cover of Whitney Houston's "How Will I Know" by Sam Smith — in addition to songs covered by Grey's fan-favorite artists and bands.

"Those are just examples, but honestly, every song is a gem," Shonda says. "Alex Patsavas is like my fairy godmother of making amazing things happen musically."

Together, they're giving new meaning to the phrase Throwback Thursdays!
