EPISODE 3: "All Adventurous Women Do The gallery where Marnie works hosts an event for the artist Booth Jonathan (played by Lonely Island member Jorma Taccone) and outside, he tells her “I want you to know, the first time I fuck you, I might scare you a little, because I’m a man, and I know how to do things.” Later, she masturbates in the gallery's bathroom as Gang Gang Dance's "Mind Killa" plays.

EPISODE 4: "Hannah's Diary" Charlie's friend Ray stumbles upon Hannah's diary while rummaging through Hannah's room, and they appropriate a passage for a song called "Hannah's Diary" when their band, Questionable Goods, meekly plays a bar later that night. It's a bizarre, hilarious scene, a modern beat poetry throwdown gone awry as Charlie reads Hannah's prognosis of his doomed relationship with Marnie.

EPISODE 5: "Hard Being Easy" Hannah's college boyfriend, Elijah, came out of the closet some time after he and Hannah had broken up. In a flashback, he and Hannah both flip out when a song comes on at a party. "Scissor Sisters!" they exclaim as "Take Your Mama" plays.

EPISODE 5: "Hard Being Easy" Marnie and Charlie meet to the soundtrack of the Knife's "Heartbeats," ensuring that the audience was zapped back to 2004.

EPISODE 8: "Bad In Bed" As Marnie goes off the rails a little bit, Jessa is along for the ride, which means they obviously end up in the plush apartment of the unbearably schmarmy venture-capitalist Thomas Jane. So that Marnie doesn't feel self-conscious when she's peeing, he throws on some of his music, which in this case is a mash-up of Len's "Steal My Sunshine" and sounds from nature. He later tries to wrangle a three-way, screaming "It's not fair!" before blasting the girls' lifestyles.

EPISODE 10: "She Did" Hannah re-enacts Beyonce's dance in the "Halo" video. It's one of Hannah's -- and Dunham's, for that matter -- most charming moments.

EPISODE 10: "She Did" In one of the series' most memorable sequences, Hannah, after a fight with Adam that ended in violence, falls asleep on the F train and wakes up in Coney Island, her purse gone. After some dawn-partiers heckle her, she walks down the boardwalk with the tinfoil-encapsulated piece of cake she saved from Jessa's wedding, eating it on the beach to the tune of Michael Penn's instrumental "Your Way," a pretty, spare piano ballad specifically commissioned for Girls.
