On the long list of songs that underscored scenes, some are truly emblematic of Grey's Anatomy, and when fans hear them, they are immediately reminded of those key moments on the show, such as when Izzy cried over Denny's dead body or when Meredith almost drowned in the icy water of Seattle's bay.

"Make This Go On Forever" By Snow Patrol

The Northern Irish/Scottish rock band Snow Patrol has a close relationship with Grey's Anatomy, as many of their songs have been featured on the show. "Make This Go On Forever," from Snow Patrol’s fourth studio album Eyes Open, is one of them. Fans might remember it particularly because it was featured in the season 3 episode "Walk on Water." As the song played, audiences watched Meredith struggle in ice-cold waters that she fell into while trying to tend to a victim of a ferry boat crash. The song was used again in the season 14 episode "Cold as Ice" while everyone waited on April to wake up after an injury.

"Timeless" By Kate Havnevik

After Meredith almost drowned, she was rescued by the love of her life, Derek Shepherd, in the episode "Drowning on Dry Land" (season 3, episode 16). As these events unfolded, the song "Timeless" by Norwegian singer Kate Havnevik played.

Havnevik seems to be a favorite of Grey's Anatomy's music supervisors. Many of her songs have been heard on the medical drama, including another fan-favorite titled "Grace," which was featured over one of the most tragic death of Grey's Anatomy season 2. Indeed, eight of her songs have been featured on the show, and some of them were even played multiple times.

"Blindsided" By Bon Iver

As all this unraveled, the song "Breathe (2AM)" by Anna Nalick, played in the background. The song is featured on Nalick's debut album Wreck of the Day, which was released in 2005.

However, it is in Cristina and Meredith's goodbye scene in the season 10 episode "Fear (of the Unknown)" that it is the most memorable.
