The talented singer and songwriter has been in the music industry for more than a decade with his bands Steel Train and Fun. and, most recently, the solo project Bleachers. With his romantic lyrics and ridiculous antics, he's become one of our biggest crushes, and now it's your turn to fall for him. Keep reading to see all the reasons to start crushing, from incredible songs — both on his own and with Taylor Swift and Sara Bareilles — to his re-creating of '80s and '90s favorites like Teen Witch and dial-up Internet.

If you like Fun., you're going to love his latest project, Bleachers. The first single, "I Wanna Get Better," is a danceable, '80s-sounding synth-pop song, and the rest of Strange Desire (out now) is just as fantastic.

He penned "Brave" and "Chasing the Sun" with Sara Bareilles, the Grammy-nominated "Sweeter Than Fiction" with Taylor Swift, Tegan and Sara's "How Come You Don't Want Me," and Christina Perri's "I Don't Wanna Break," among others.
"Taylor Swift is cool, because she's the closest thing today that hearkens to Michael Jackson — to great, great pop music," he recently told GQ. "There's a difference between her and Gaga and Katy Perry and Lily Allen and all that. It all feels throwaway, comparatively."

In Steel Train's "Fall Asleep," he sings, "And when I fall asleep, I want to see you there in a dream. I want to take you to the heart of every place that I've been."
In this song, he sings, "If you're feeling small, I love your shadow. When the lights go down, I will stand right beside you."
In another track called "Wake Me" (that may or may not be a romantic ode to Lena), he sings, "I'd rather be sad with you than any other girls but you. I can't believe I captured your heart."

If we can't have him, she definitely should. "On my first date with Lena, I told her everything about my whole life," he told Vulture about their relationship. "Because when you really like someone, you want them to know everything about you."
