With 'Somethin' Bad,' the stars score the first No. 1 by teamed-up solo women in more than two decades. Plus, Kenny Chesney achieves his 45th top 10 with 'American Kids'

Miranda Lambert and Carrie Underwood put on an impressive display of girl power on Billboard's Hot Country Songs chart, as "Somethin' Bad" vaults 18-1 with top Streaming Gainer honors. The track also flies to the top of Country Streaming Songs (11-1) with a 506 percent gain to 4.2 million U.S. streams, according to Nielsen BDS, after its official video premiered on June 26.

While streaming accounts for 50 percent of its Hot Country Songs chart points, "Bad" also gains in sales and airplay. It bounds 10-4 on Country Digital Songs (60,000 downloads sold, up 86 percent, according to Nielsen SoundScan), marking its best rank and sales sum since it debuted atop the sales tally dated June 7 – after Lambert and Underwood had premiered the duet on the Billboard Music Awards (May 18). On Country Airplay, "Bad" bullets for a second week at its No. 25 highpoint so far (15 million impressions, up 12 percent).

"Bad" is Underwood's 13th Hot Country Songs No. 1 and first since "Good Girl" in June 2012 (and first since the chart switched from an airplay-only methodology to encompassing airplay, sales and streaming). It's Lambert's fifth. It's the chart's first No. 1 featuring a female artist since Lambert and Keith Urban's "We Were Us" led for three weeks in November/December (her most recent No. 1 before "Bad").

How rare is it for solo women to team up for a Hot Country Songs No. 1? It had happened only twice before since Billboard launched its first multi-metric-based country chart in October 1958: Dolly Parton, Linda Ronstadt and Emmylou Harris led the May 16, 1987, list with "To Know Him Is to Love Him," and Reba McEntire and Linda Davis spent a week at No. 1 with "Does He Love You" (Nov. 6, 1993; Davis is the mother of Lady Antebellum's Hillary Scott, who was seven years old at the time).

The 18-1 blast for "Bad" is also uncommon, as just three other No. 1s have reached the summit with greater climbs. Luke Bryan's "That's My Kind of Night" rocketed 35-1 (Aug. 31, 2013); Taylor Swift's "We Are Never Ever Getting Back Together" flew 21-1 (concurrent with the chart's Oct. 20, 2012, switch to three-tiered measurement); and, Johnny Cash's "Daddy Sang Bass" bounded 19-1 (Jan. 4, 1969).

Lambert also returns to the top of Billboard's Top Country Albums chart with her fifth album, "Platinum," which rebounds 2-1 (29,000 sold, down 15 percent). The set had fallen to No. 2 last week after spending its first two frames at No. 1; it's sold 305,000 to date.

Lambert is the first female artist to dominate Hot Country Songs and Top Country Albums simultaneously since Swift doubled up with "Never " and "Red," respectively, on Jan. 12, 2013.

ALL 'AMERICAN': Just in time for July 4, Kenny Chesney charges 17-6 on Hot Country Songs with "American Kids," the chart's top Digital Gainer. It roars 7-1 on Country Digital Songs (74,000, up 87 percent) following its first full week of retail availability. It also enters Country Streaming Songs at No. 14 (624,000, up 392 percent); its official clip premiered Monday (June 30), likely translating to even greater streaming gains next week. On Country Airplay, "Kids" climbs 27-20 (18 million, up 39 percent).

"Kids" is Chesney's 45th Hot Country Songs top 10. Dating to his first week in the top bracket (with "Fall in Love," June 24, 1995), he passes Tim McGraw (44) for the most top 10s among all acts in that span.
