iTUNES GETS ON YOUR BRAINWAVE: We woke up this morning, to paraphrase the old blues song, and found the iTunes album chart didn't look the way it did yesterday. The new one from Epic's Sara Bareilles, The Blessed Unrest, had vaulted to #1, ahead of Jay-Z's Magna Carta (which will be the week's sales champ, no doubt). Pop kid Cody Simpson occupied #3, followed by Cash Money/Republic rapper Ace Hood, whose Trials & Tribulations is studded with guest stars; next came Vanguard's Matt Nathanson, WB rockers Avenged Sevenfold, yet another Kidz Bop Kids (#24, but who's counting?), Vol. 2 of The 20/20 Experience by RCA's Justin Timberlake and another hip-hop debut, this one by Kevin Gates. Was it all a dream? Well, rounding out the album chart was the meditation EP Change Your Mind: Music for Brainwave Entrainment (DPM), so you tell us. On the singles side, things look reassuringly familiar: Star Trak/Interscope's redoubtable Robin Thicke remains at #1, with RCA's Miley Cyrus twerking at his tail. The rest of the Top 10 is mostly the usual top-selling suspects, but we note the ascent of "Cups" from UMe's Pitch Perfect ST (sung by star Anna Kendrick) and Voice Season Four champ Danielle Bradbery. Speaking of brainwave entrainment, it's time for more coffee. (7/16a)
