Congratulations to our man Bruno Mars, who came out on top in our latest About to Pop battle. This upcoming weekend, fans of the crooner will get to hear his song 'Runaway Baby' bumping from their radios. Mr. Mars might be the reigning champ this week, but who will get some airplay on next weekend's PopCrush Top 20 countdown? This week, fans can vote for tracks by Adam Lambert, the Wanted and more.

Adam Lambert appears in this week's About to Pop with his single 'Never Close Our Eyes,' which has a more uptempo, dancey feel as opposed to his first release 'Better Than I Know Myself.' Lambert has some competition in the form of the Wanted, who are also being featured this week with their new single 'Chasing the Sun.' PopCrush readers can also vote for former 'American Idol' contestant Stefano Langone's debut single 'I'm on a Roll' (featuring New Boyz and Rock Mafia), John Mayer's simply beautiful 'Shadow Days,' and finally, Havana Brown's Pitbull-featured club banger 'We Run the Night.'

The time to vote has arrived! If you aren't familiar with some of the tracks, you can listen to each of this week's About to Pop contenders below. So, who will it be? Are you digging Adam Lambert's new single? Or have the Wanted won you over? Perhaps John Mayer's guitar strumming is absolutely irresistible to you? Or are Langone and Brown's dance floor anthems have you moving to the music? You can vote until 3PM EST on April 30, and be sure to tune in to PopCrush's weekly radio show to hear the winning track!

Rules: The song with the most votes will get aired on the PopCrush Top 20 syndicated radio show, which airs on over 20 radio stations across the United States.
