Do you like your legs hot, or is it more important that the person who owns them knows how to use them? You have to choose between the two in this edition of Clash of the Titans, which puts Rod Stewart up against ZZ Top in a battle of the rock 'n' roll gams.

Stewart struck first in this battle, releasing 'Hot Legs' as a single from his 1977 album 'Foot Loose & Fancy Free.' A medium-sized hit in the U.S., it peaked at No. 28 on the Billboard charts during its radio run, although it was more successful in the U.K., where it reached No. 5. ZZ Top's 'Legs' didn't arrive until 1983, when it surfaced as a track on the band's 'Eliminator' album. Released as a single in 1984, it peaked at No. 8, also spinning off a hit dance remix that emphasized the song's synth-driven sound.

Separated by several years and a major difference in sound, the two songs still boast a handful of similarities; for one thing, they both boast leg-centric videos, and ZZ Top's 'Legs' clip -- one of several starring the band members as sort of mojo-dispensing rock 'n' roll genies -- was one of the more heavily played hits of the early '80s. Both songs were also later covered by Tina Turner, who knows a thing or two about hot legs and how to use them.

So which 'Legs' gets your vote in this Clash of the Titans matchup? Check them both out below, and remember: you can cast a ballot once an hour between now and when voting ends on Sunday, Aug. 24, at 11:59PM.
