Carrie Underwood scores her fifth consecutive top five album, as her Greatest Hits: Decade #1 bows at No. 4 with 103,000 units (94,000 in pure album sales). This is the first best-of collection for the singer, who previously logged four albums that reached the top two: her Some Hearts debut (No. 2 in 2005), followed by three No. 1s: Carnival Ride (2007), Play On (2009) and Blown Away (2012).
Underwood's latest set is the highest-charting greatest hits album since the chart dated Aug. 25, 2012, when Frank Sinatra's Nothing But the Best re-entered at No. 3 (thanks to deep discounting by Amazon MP3). Underwood logs the biggest sales week for a best-of since Whitney Houston's Whitney: The Greatest Hits shifted 112,000 on the chart dated March 17, 2012 (in the wake of Houston's death), and the biggest sales debut for a hits set since Sinatra's Nothing arrived with 99,000 (at No. 2) on the May 31, 2008 chart.
Taylor Swift’s “Blank Space” spends its fifth straight week at the top of the Weekly Combined Stream Playlist, with 12.2 million streams. Nicki Minaj’s “Only” leaps 32-2, Hozier’s “Take Me To Church” moves 5-3 and Meghan Trainor’s two singles round out the top five.
Big movers include Mark Ronson’s “Uptown Funk” 22-15, Ed Sheeran’s “Thinking Out Loud” 25-17, James Newton Howard’s “The Hanging Tree” 151-38 and Ariana Grande’s “Santa Tell Me” 127-56.
With those huge airplays and streaming, Blank Space will atop BBH100 at least 2-3 weeks depending on how much the lead on digital songs UF and TMTC can build on BS. If the lead small, BS will remain #1 at least another 4 weeks considering BS still building its airplay and the weak streaming of UF. Probably TMTC will be #1 first followed by UF. But we will see then
Taylor's "1989" era is shaping up to be INSANE. OMG.
Like "Shake It Off" spent 4 weeks at #1, which is a lot for a Pop girl's lead single to begin with. However, the second single "Blank Space" is on it's 5th week at #1!!!! That's amazing! Like the first two lead singles having 4+ weeks atop is hard to come by nowadays.
"Style" needs to be the third single, and if it doesn't go #1, it will be a travesty.
