Is it even Grey's Anatomy [1] if you go an episode without crying to a song and then immediately looking it up afterward? The show is notorious for its use of indie-rock artists and melancholy Sleeping at Last covers. For season 15, the long-running medical drama enlisted emotional tracks from more obscure artists, including British indie-pop chanteuse Bishop Briggs and folk-rock singer Tommy Ashby. Most notably, it paid respect to Dia de los Muertos with an emotional Spanish cover of Snow Patrol's "Chasing Cars," [2] aka the ballad that made you cry your eyes out when Denny Duquette and Derek left the show. Read ahead to find out our favourite songs from the 15th season [3] — so far!

"Out of the Blue" by Fleurie

"Someone to Watch Over Me" by Sleeping at Last
