Since Adam Lambert's domination over PopCrush's Sound Off series has come to an end, it's time for a new batch of contenders to go head-to-head in a battle of the songs. Today, two pop-rock outfits are challenging each other with two brand-new singles -- Neon Trees and their track 'Everybody Talks' are going up against the Asteroids Galaxy Tour's tune 'Heart Attack.'

Just like they did with their smash single 'Animal,' Neon Trees once again prove that they have an ear for producing catchy pop-rock songs. 'Everybody Talks' starts off with some barbershop quartet-esque singing before switching to some infectious verses and a rockin' chorus. The song rises and falls as the tempo slows down on the verses before kicking it into high-gear on the heavier refrain.

Likewise, Danish pop-rockers the Asteroids Galaxy Tour know how to get fans singing and dancing along, as exhibited in their new lighthearted tune 'Heart Attack.' Singer Mette Lindberg's voice leaves a lasting impression as the guys in the band get listeners bopping their heads to the bubbly beat.

So, which song are you feeling more? Cast your vote for either Neon Trees' 'Everybody Talks' or the Asteroids Galaxy Tour's 'Heart Attack' below. Voting closes on Jan. 18 at 8AM EST.
