"Everything is different the second time around," sings Regina Spektor during the opening credits of Orange Is the New Black — just like the show's music in Season 2.

Her "You’ve Got Time" theme song, written specifically for Netflix's prison comedy series, sets the tone for every episode. But this sophomore season showcased even more spectacular song selections that added emotional power to certain scenes.

In the first episode, when imprisoned lead character Piper Chapman had no clue why guards put her on a plane or where she was going, Andrew Bird's instrument-laden "Pulaski at Night" kicked in just as handcuffed Piper saw the Chicago skyline from her airplane seat. "Come back to Chicago, city of, city of light," Bird belts in a nonchalant, half-glass-empy fashion.

The music choices got some love on social media, with some viewers begging for people to assist them in figuring out what song they had just heard. The cover of Christina Aguilera's "Beautiful" at the end of second episode had fans scratching their heads. Netflix helped Mashable pin down the artist: an Italian artist named Discover.

Here's a list of 25 songs used this season (including the prison sing-a-long selections from episode 12), ending with Miss Rosa's finale anthem "(Don't Fear) The Reaper."
