Hunter Hayes has truly found his groove. The 21-year-old singer just sold out two nights at the historic Ryman Auditorium, and is now celebrating his first No. 1 album with the deluxe version of his self-titled debut, 'Hunter Hayes (Encore).' 

The Grammy-nominated and and Platinum-selling music prodigy should be going 'crazy' over the demand for his bonus album, as it's been fast and furious, propelling Hayes to the top of the charts. The album went to the No. 1 spot on Billboard’s Country Chart, and the current upbeat single, 'I Want Crazy,' is rapidly approaching Top 5, selling over 100,000 copies last week alone.

Hayniacs always rise to the challenge -- especially since Hayes treats them so well, even debuting the album at an exclusive fan listening party. The newest album features eight new or re-recorded songs, in addition to collaborations with pop star Jason Mraz and country songstress Ashley Monroe, who will be joining Hayes on his Lets Be Crazy Tour this fall, with 24 shows in 21 cities.

Even though he's an incredibly busy and in-demand artist, Hayes continues to showcase his adorable personality, which makes his fans just love him even more. Recently, he gifted 'The Voice' winner Danielle Bradbery with his favorite guitar -- it really doesn't get much sweeter than that.

Hayes is not only No. 1 on the charts, but also one of the nicest, most thoughtful musicians in the industry. Here's to continuous encores for the rising star.
