The pair does what no other twosome has done in the chart's 50-year history: debut at the summit with a first album. Plus, chart action for Josh Thompson, Brad Paisley, Florida Georgia Line and more

Dan + Shay become the first rookie duo to arrive at No. 1 on Billboard's Top Country Albums chart with a debut set, as "Where It All Began" enters with 29,000 sold, according to Nielsen SoundScan. (It bows at No. 6 on the all-genre Billboard 200.)

While the No. 1 launch is a first in the tally's 50-year history, Dan + Shay (Dan Smyers and Shay Mooney) also mark just the third duo to reach No. 1 with a full-length debut album, following Big & Rich's "Horse of a Different Color," which reached the top in its 16th chart week (Sept. 4, 2004), and Florida Georgia Line's "Here's to the Good Times," which finally reigned in its 28th week (June 29, 2013). The new leader is the first studio album of new material by any duo to start at No. 1 since Sugarland's "Love on the Inside" (Aug. 9, 2008).

Dan + Shay's start is fueled by lead single "19 You + Me," which reaches the top 10 on Hot Country Songs (11-7). The album benefited from a week-long streaming preview on Spotify (which began March 25), alongside release-week stops on "The Ellen DeGeneres Show" and ABC's "Good Morning America."

THOMPSON'S 'TURN': Josh Thompson logs his second top 10 on Top Country Albums with sophomore set "Turn It Up," which opens at No. 7 with 9,000 sold. Thompson's first album, "Way Out Here," entered and peaked at No. 9 with 15,000 (March 13, 2010).

"Cold Beer with Your Name on It," the lead single from the new release, peaked at No. 32 on the March 22 Hot Country Songs chart.

TUBE TOPS: Watch for spikes on next week's charts (dated April 26) driven by the April 6 Academy of Country Music Awards, broadcast on CBS.

Even before a full-week of post-ACMs sales, some titles already gain. Co-host Blake Shelton's "Based on a True Story…" jumps 11-6 on Top Country Albums with Greatest Gainer honors (10,000 sold, up 100 percent) and fellow co-host Luke Bryan crowns Country Digital Songs with "Play It Again" (2-1; 88,000, up 40 percent). The latter title earns Digital and Streaming Gainer nods (964,000 U.S streams, up 75 percent, according to Nielsen BDS) on the sales/airplay/streaming-based Hot Country Songs chart, where it reaches a new peak (5-3). Shelton and Bryan also performed on the ACMs telecast.

Country Digital Songs also shows ACMs-related spikes for Eric Church's "Give Me Back My Hometown," (7-5; 41,000, up 30 percent) and Hunter Hayes' "Invisible" (16-12; 29,000, up 46 percent).

'RIVER' ROLLS: Coordinated hourly play at Clear Channel-owned stations on April 4 (and just three days of airplay overall) helps lift Brad Paisley to a No. 29 launch on Country Airplay with "River Bank."

The lofty debut is Paisley's third-highest, trailing only that of "Southern Comfort Zone," which arrived at No. 25 on the Oct. 6, 2012, chart, and "Then," which roared in at No. 26 (April 4, 2009).

The West Virginia native performed "River" in a taped segment that aired on the ACMs. The track is the lead single from his forthcoming 10th studio album, for which no title or release date has yet been announced. The track was released digitally on April 4, selling 4,000 downloads at the tail end of the tracking week (which ended on April 6) and helping spur a No. 36 debut on Hot Country Songs. A sturdy surge is expected following the song's first full week of sales, to be reflected on next week's Hot Country Songs and Country Digital Songs rankings.

'ROLL' ON: Florida Georgia Line lands its fifth Country Airplay top 10 with "This Is How We Roll" (featuring Luke Bryan), which shoots 11-8 in its 12th chart week. The duo, which has reigned in its first four attempts, has made better time to the upper tier just once, when previous single "Stay" entered the top 10 in its 11th week (Dec. 7, 2013).

Florida Georgia Line and Brooks & Dunn are the only two acts in the Country Airplay chart's 24-year history to take each of their first four singles to No. 1. A solo share of the tally's history awaits FGL if "Roll" can become its fifth career-opening topper.

On Hot Country Songs, "Roll" rules for a fourth week, holding at its No. 2 highpoint on Country Streaming Songs (1.4 million U.S. streams, up 5 percent, according to BDS) and dipping to No. 2 on Country Digital Songs after four non-consecutive frames in top, although with a 1 percent gain to 78,000.

'AUTOMATIC' HIT: Multiple Academy of Country Music Awards winner Miranda Lambert adds another trophy to her mantle, for her 10th Country Airplay top 10, as "Automatic" flies 14-10 in its ninth week. Lambert scores her quickest top 10 ascent unaccompanied by another act, surpassing a pair of 10-week climbs with "The House That Built Me" (2010) and "Baggage Claim" (2011). Her chart-topping duet with Keith Urban, "We Were Us," cracked the top 10 in its sixth chart week (Oct. 26, 2013).
