"Once a Day" made Smith a major star in country music, nominating her for a series of Grammy Awards, including "Best Female Country Vocal Performance" and "Best New Country Artist." It was released on Smith's self-titled debut album in March 1965, which also reached No. 1. The single helped gain Smith a series of major hits under RCA Victor in the 1960s. Her follow-up single, "Then and Only Then" (released in 1965) reached No. 4 on the "Billboard" Country Chart, and a series of unbated Top 10 hits continued until mid-1968, including "If I Talk to Him," "Ain't Had No Lovin'," and "The Hurtin's All Over." Smith would continue on to have nineteen more Top 10 singles during her career.
