Billy Currington continues to dominate the country singles chart for Billboard‘s first issue of 2006. Currington spends a second week at No. 1 with “Must Be Doin’ Somethin’ Right,” his first single to top the chart. The country singles chart for Billboard‘s Jan. 7 issue also reflects two debuts — Rascal Flatts’ “What Hurts the Most” (at No. 33) and Keith Anderson’s “Every Time I Hear Your Name” (at No. 49). Josh Gracin also had two holiday tracks that made it to the chart.
