Guns N' Roses' ode to a Hollywood madam goes up against a mind-expanding Beatles classic in the second round of our Rock Star Wars battle.

To try and fill our days between now and the new Star Wars: The Force Awakens movie, we’ve tracked down 32 space-themed classic rock songs and paired them off against each other in a series of intergalactic battles. The field will be halved every week based on your votes, until only the spaciest song in rock history is left.

How you vote here will probably depend largely on how you'd most like to travel through space — hurtling along with "Rocket Queen," having Axl Rose's howling and a smattering of sex noises as your guide, or drifting peacefully into the void with "Across the Universe" while repeating a transcendental meditation mantra along with John Lennon.

Either way, you can hardly go wrong, as demonstrated by the lopsided victories racked up by each of these contestants in the opening round. Guns N' Roses pulled off a landslide against Monster Magnet's "Space Lord," piling up roughly 75 percent of the vote, while the Beatles faced a similarly outmatched opponent in Hawkwind's "Silver Machine."

So, which of these songs will emerge victorious from this round? It’s your choice. You can listen to both tracks below, and vote once per hour in each of the this round’s Rock Star Wars battles until voting ends Nov. 30 at 11:59PM ET. Your choice for our Rock Star Wars champion will be revealed on Dec. 22, 2015.
