How Taylor Swift Has Ruled the Charts: From 'Tim McGraw' to 'Blank Space'
YOUNGER ACTS GOT SIGNED
With a few exceptions -- most notably Tanya Tucker and LeAnn Rimes -- country labels didn't sign teenagers. But lately, country is spotlighting younger, less grizzled faces, including Maddie & Tae (both 18), RaeLynn (20), Kacey Musgraves (26), Lucy Hale (25) and Hunter Hayes, who signed to Atlantic Records Nashville in 2010 when he was 19.
