Listen to Jason Aldean on iHeartRadio

Jason Aldean admits his Billboard Music Award nomination in the all-genre Top Male Artist category is particularly meaningful to him.  The singer says he feels "really proud to be the guy" who gets to "wave that flag for country music" in the category. 

Aldean explains that he's been focused on his "Night Train" tour that the nominations totally took him by surprise.  But he's extending his thanks to everyone who has bought a ticket or downloaded an album, adding that he'll do his best to "represent and make y'all proud." 

Aldean is vying for the award along with pop stars Justin Bieber and Bruno Mars and rappers Drake and Flo Rida. 

Top Male Artist is one of three nominations for Aldean.  He's also in the running for Top Country Artist and his CD "Night Train" is up for Top  Country Album. 

The 2013 Billboard Music Awards will take place in Las Vegas, and air on ABC on May 19th.
