The Glamberts have done it again! Adam Lambert defeated Train yesterday in one of the most overwhelming victories we have seen in the Sound Off as of yet. Lambert's new single 'Better Than I Know Myself' knocked Train's latest release 'Drive By' out of the running with more than 90% of the fan votes. Now Lambert will face off against guitar-strumming crooner Jason Mraz and his new tune 'I Won't Give Up,' which is currently at No. 1 on iTunes' Singles chart.

On both of these tracks, Lambert and Mraz deliver their own variations of a love song, with both of the men singing about the difficulties one can encounter in a romance. Mraz's voice is emotional and sort of beautifully frantic at times on the slower, stripped-down track, which is about trying your hardest to salvage a broken relationship. Lambert also sings about a relationship on the rocks over beating drums and synths -- bringing his song full circle as he pours his heart out to his lover with impressive falsetto notes during the chorus.

So, which song left a lasting impression on you? Vote for either Adam Lambert's 'Better Than I Know Myself' or Jason Mraz's 'I Won't Give Up.'

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!
