Love and Theft is on a roll. The Nashville duo's new song 'Runnin' Out of Air' easily topped the new single by Toby Keith yesterday and last night on Taste of Country Nights radio. Today, the catchy pop-country song will square off against a Hollywood star who's turned country. 

Hayden Panettiere plays Juliette Barnes on the ABC drama 'Nashville.' Her first single from the series is the uptempo, done-me-wrong 'Telescope.' Early on, the song is getting a warm response from radio. It will be interesting to see if the actress-turned-singer has developed a strong enough fan base to push her to a new round on Friday.

Listen to clips of both Love and Theft's and Panettiere's songs and vote for your favorite here. You can vote once every hour online, so come back and vote often to be sure your artist wins. Hear the full versions of the songs tonight after 10PM on Taste of Country Nights. Help your favorite song win by placing additional votes at (888) 678-9995. Call as many times as you like! You can listen to the show online through any of the 41 radio stations that carry it. Voting will end tonight at 10:40PM CT.
