Rascal Flatts' recent hit 'I Won't Let Go, has been certified Digital Gold by the RIAA after sales exceeded 500,000 downloads. The song recently became the band's 13th career No. 1 when it topped the Mediabase/Country Aircheck country singles chart back in May. The accolade makes Rascal Flatts the most awarded country vocal group of the past decade.

'I Won't Let Go' was penned by hit writers Steve Robson and Jason Sellers, and is the second consecutive No. 1 single for Rascal Flatts from their current Big Machine Records album 'Nothing Like This.'
