Meet Addy, the future star of karaoke nights across America. This little beam of sunshine knows every word to Sugarland's 2009 hit 'It Happens,' and has choreographed a dance to further entertain her followers on YouTube. The nearly three-minute-long video is a joy to watch from start to finish. 

Addy has a number of other country covers at her channel on YouTube, including songs from Jake Owen and Lady Antebellum. She's also stretched beyond Nashville to perform hits by Skrillex and LMFAO. Fans of early '90s pop music may appreciate her cover of Vanilla Ice's 'Ice Ice Baby.'
