Although Demi Lovato put up a good fight in yesterday's Sound Off, Adam Lambert defeated the teen queen's new single 'Give Your Heart a Break' with his new moving ballad 'Better Than I Know Myself.' So, can Adam's troop of loyal Glamberts take him to the top again? Today, the eyeliner-wearing vocalist and his new tune will take on Train's latest single 'Drive By.'

On 'Better Than I Know Myself,' Lambert delivers an emotive vocal performance that leaves a lasting impression. The former 'American Idol' contestant travels into the falsetto range as he belts out the 'Better Than I Know Myself' chorus over clashing drums. Conversely, Train's new single 'Drive By' is an uptempo, sing-along. Singer Pat Monahan croons the bubbly, infectious chorus as the rest of the Train dudes strum their guitars, pound rumbling drums and clap in time with the beat.

Which song has won you over? Vote for Lambert's 'Better Than I Know Myself' or Train's 'Drive By' below.

Rules of ‘Sound Off’:
There’s only one rule for our ‘Sound Off’ series: If a song remains the reigning champ for five straight days, it is retired to PopCrush’s ‘Sound Off’ Hall of Fame. With tons of great tracks coming out everyday day, we have to give other artists a chance to win!
