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.
