Johnson released an album in 2008, "That Lonesome Song", which was only made available online. The album drew the attention of Mercury Nashville Records, who signed him to a record deal in 2008. His first single for the label, "In Color", was released in March 2008. This song, which Johnson co-wrote with Lee Thomas Miller and James Otto, entered Top 40 in June 2008, and "That Lonesome Song" was released on CD in August of that year. "In Color" peaked at No. 9 on the Country chart in January 2009 and was followed a month later by "High Cost of Living", which managed to crack the Top 40, but only reaching No. 34. By April 2009, "That Lonesome Song" was certified Gold by the RIAA.
