PTX #1

RETAIL BOUGHS: It's not even Black Friday yet, but That's Christmas to Me, the new holiday set by RCA's a cappella phenoms Pentatonix, has hit #1 on the iTunes album chart. Other yuletide collections selling briskly include Holiday Wishes by Warner Bros.' Idina Menzel (#8), the prior Pentatonix seasonal set, PTXmas (#14), and Michael Bublé's perennial Christmas (on Reprise, at #16). Now if you'll excuse us, we're going to snarf down our Thanksgiving plate and then get started on the eggnog. Noël! (11/27p)
