Billboard talked with musicians, actors, directors, and comedians about their ultimate love songs. 

Katy Perry
“I invite all! If I could do a call and response to that, it’s like, ‘I ain’t got no type, I just want someone on the level that I like.’ Did I really just say ‘No Type’ is my favorite love song?”

Iggy Azalea
“I love 50 Cent, “21 Questions.” (laughs) When I was a teenager I used to listen to that all the time just like, ‘I wish I had a love like 50 Cent and Meagan Good in the video.’” So yeah, that’s a funny one.”

Joey Badass
“Do For Love,” 2Pac. That shit tingles. Like if I would’ve heard that beat [before Pac], I would’ve picked that beat. It literally vibrates my soul. My whole aura. It changes the color of my work when it comes on. I feel so sentimental and when 2Pac puts his accompaniment on it it takes it to another level. [Starts rapping] ‘I shoulda known you was trouble right from the staaaaaart…’”

Diplo
“You know what I love? The Flamingos’ ‘I Only Have Eyes for You.’ That’s one of the best songs ever made.”

Sarah Silverman
“‘Long Ride Home’ by Patty Griffin, about a woman riding home from her husband’s funeral. I like heartbreaks.”

Chris Pine
“My brain’s all over the place. I’m just thinking like, Bruce Springsteen. It’s not a love song, I was thinking about this lyric, ‘Chicken man’ [from ‘Atlantic City’] (laughs).”

Spike Lee
“‘Ribbon in the Sky’ by Stevie Wonder. Stevie Wonder sang it at my wedding to my wife, Tonya Lewis. Can’t beat that. Stevie was very gracious to me to bless us with that wedding gift.”

Alexandre Desplat, Oscar-nominated composer of The Imitation Game and The Grand Budapest Hotel
“David Raksin’s ‘Laura’ [because] it’s [the theme of] a film where music is doing everything. Music is showing the audience the invisible.”

John Legend
“Stevie Wonder’s ‘Ribbon in the Sky’ is one of the first ones I go to.”

Gwen Stefani
“I love all of them. I’m a Power 103.5 ‘Love Songs On The Coast’ kinda person. The cheesier the better. You can’t go too far.”

Cobie Smulders
“Anything by [singer-songrwiter] Brett Dennen.”

Keith Urban
“Oh, hands down, [The Beach Boys’] ‘God Only Knows.’ That’s one of the greatest love songs ever. That’s just potent simplicity. To open up a song with ‘I might not always love you,’ I’m in. That’s fantastic. The interesting thing about love songs is at their core, they are usually just intensely codependent, pathetic comments and acknowledgements that you are just a complete codependent, pathetic person.”

B.o.B.
“Right now it’s [Nick Jonas’] ‘Jealous.’ I remember when I first heard it, it was like, ‘Damn.’ I guess it’s not a love song, it’s a song about love. But it just feels real, man. I loved it so much I put a verse on it — you can check it out on my SoundCloud.”

Chiwetel Ejiofor
“‘Famous Blue Raincoat’ by Leonard Cohen. I like poetic, weird love songs.”

Kevin Bacon
“Van Morrison’s ‘Crazy Love’ was our first dance at our wedding so that’s the first one that pops into my mind.”

Aloe Blacc
“My favorite love song for Valentines Day is D.J. Rogers’ ‘If You Didn’t Love Me.’”

Kid Cudi
“Man, I don’t really like love songs, but Case’s ‘I’m Missing You’ — remember that? [Starts singing.] You know the song! Hey, Google it!”

Scott Weiland
“‘Somebody’ by Depeche Mode, it was one of the wedding songs that my wife and I had playing when we were getting married. It’s also an amazing song; Martin Gore is awesome on it.”

Zach Chance of Jamestown Revival
“I’m going a little different because we were jamming on the streets, we were a little tipsy last night and it’s Whitney Houston’s ‘How Will I Know.’ That’s a jam. It embodies my spirit. So that’s my love song.”
