Billboard Country Number-One Albums, 2004 onwards Quiz

Every distinct album represented at number one on Billboard's country year-end album chart from 2004 onward: 16 albums across 22 chart years, taken from the same published table as the complete run. 6 chart years repeat an album already represented, so each winner appears once under its first listed year. Name each album from that first year, with the artist and title's first letter available on easier settings, or sort a 15-album selection chronologically. Parsed verbatim from the published year-end table; no answer is named here.
