Fall TV is in full swing, which means plenty of cliffhangers, viral moments and funny quips. But it also means the return of can't-get-out-of-your-head theme songs. 

Fall TV: 8 Things We Can't Wait to See

We polled some of Billboard's staff on their personal all-time favorite theme songs, and we want to hear your favorites as well, from old-time faves such as The Brady Bunch or Gilligan's Island to newer ones like Veronica Mars and The O.C.

Vote for your favorite below (or write in your option), and then read our (unscientific) picks.

All That
The All That theme is definitely one of my all-time favorite TV theme songs. As a '90s kid, there was nothing like coming back home from a hard week of second grade to a Friday night episode of All That. Perfecting Left-Eye’s rap was like a rite of passage. --Aggi Ashagre

Veronica Mars
The Dandy Warhols' "We Used to Be Friends" wasn't written specifically for Veronica Mars, but its opening line ("A long time ago, we used to be friends") perfectly encapsulates the show's story of a once-popular girl who becomes a social pariah -- and then a P.I. The theme song saw a few incarnations over the years: First, a darker version to match the third (and final) season's moodier themes and then an acoustic take performed by a street busker in 2014’s Kickstarter-funded Veronica Mars movie. --Katie Atkinson

Good Times
The theme song for Good Times translated the show's scrappy survive-by-any-means message into a hooky, unshakeable tune. Its mood is optimistic, even in the face of "temporary layoffs" and "easy credit ripoffs" -- and few shows could pull that off. --Steven Horowitz

Star Trek: The Next Generation
A thought-provoking ode to humanism, Star Trek: The Next Generation posits the rare optimistic view of the future in sci-fi. The open-minded excitement of exploration is perfectly captured by the show's thrilling orchestral fanfare, adapted from earlier compositions by Jerry Goldsmith and Alexander Courage. Listen to it and get jazzed about humanity's future(s). --Joe Lynch

Pokemon
My favorite TV theme song is definitely the Pokemon theme because it makes me feel like I can take over the world. I love how it’s from the late ’90s but sounds like it was from the montage of an action film in 1985. Those guys wouldn’t let time hold them back. --Chris Payne

The O.C.
Not only did The O.C. introduce the masses to tons of great music over its four-year run, but the instantly recognizable theme song -- Phantom Planet's "California" -- was able to instantly relay to viewers the easy California attitude, beach fun and promise of good things to come. --Erin Strecker

​Friends
So no one told you that the Friends’ theme was going to be this way -- meaning an iconic and catchy tune that became a legitimate radio hit in 1995. The Rembrandts’ song was literally there for the show over its 10-year run and remains an unforgettable part of pop culture. --Denise Warner
