Sara Evans has one of the most distinctive voices in country music, and tonight she'll also have a spot on TV as she joins host Nan Kelley on GAC's "Top 20 Country Countdown."

Sara has plenty to talk about, starting with her recent engagement to Jay Barker, a former University of Alabama quarterback who now hosts a sports-talk show on a radio station in Birmingham. Sara will also unveil a bit about her touring plans as she and Nan work their way through the 20 biggest videos in the land. For the second week in a row, Carrie Underwood and Taylor Swift own four of the top five slots on the countdown, though they've changed places just a bit.

Top 20 Country Countdown counts down the week's top country videos from No. 20 to No. 1 as voted by viewers on each week on GACTV.com. A new countdown premieres every Friday at 8 p.m. ET on GAC and airs again Saturdays at 10 a.m. and 5:30 p.m. ET; Sundays at 1 p.m. ET; and Mondays at 10 a.m. ET. Viewers can vote for their favorite videos, as well as purchase Top 20 artists' albums and ringtones at GACTV.com.
