While the top three (Gaga, Bieber, Rihanna) on Billboard's Social 50 remain unchanged on this week's chart , the social buzz generated by Avenged Sevenfold, Adele, LMFAO, Christina Grimmie and Lil Wayne climbed significantly.
U2 back on stage after two months off for Bono's injured back, Jay-Z memoir to be released, Arcade Fire tops UK album chart, Avenged Sevenfold talks about their "Nightmares".
Next week on the Billboard 200 albums chart, rock band Avenged Sevenfold is gunning for a possible No. 1 debut with its new album, "Nightmare." Initial sales projections from industry prognosticators suggest that the album could sell in the range of 160,000 to 180,000 by week's end on Aug. 8.
