BIG MAC!!

That’s right, just like we said last week, Rostrum Records rapper Mac Miller’s Blue Slide Park, distributed digitally by INgrooves and physically by Fontana, will debut at #1 smack dab in the middle of Q4, with estimates of between 175-185k, which might even be conservative.

This is a triumph of social networking and good, new-fashioned viral marketing, as Malcolm McCormick, the son of a Christian architect father and Jewish mother photographer, transforms his combined 2.7 million Twitter, Facebook and MySpace followers into an impressive debut.

This is Miller’s physical full-length debut after a series of well-received digital mixtapes, an EP, On and On and On Beyond, and a smash video in “Donald Trump.”

Those figures are based on one-day sales figures from music retailers, some of whom are even holding out at brick-and-mortar outlets, though it’s looking like digital might even surpass physical on this release.

Also on tap, Chop Shop/Atlantic’s Twilight: Breaking Dawn soundtrack, which arrives before the film’s Nov. 18 release, should do between 100-110k.

Capitol/EMI’s Now 40, the latest in the compilation series, should also debut in the low six figures, with a projected total of 100-110k.

Sony Music Latin star Romeo Santos’ solo debut, Formula Vol. 1, which includes cameos by Lil Wayne, Pitbull, Usher and George Lopez, will debut with between 65-75k after being #1 on iTunes Latin Music chart and #4 overall. Santos will perform the current single, “Promise,” with Usher tomorrow night on the Latin Grammy Awards.

Syco/Columbia’s Il Divo album, Wicked Game, their first since 2008’s The Promise, will bow with between 50-60k.

Reprise Chicago metal mavens Disturbed’s Asylum, their follow-up to 2008’s Indestructible, is on target for a first-week total of 35-40k

Veteran Strange Music Kansas City rapper Tech N9ne’s Welcome to Strangeland, the fourth in his “Collabos” series, was released on the hip-hop star’s 40 th birthday and is looking at between 24-27k.

Sour Mash/Mercury artist Noel Gallagher’s High Flying Birds debuts with 12-15k for the Oasis guitarist.

Album sales were up 10% vs. last week, up 14% vs. same week last year and up 3% year to date.

Track sales were up 4% vs. last week, up 5% vs. same week last year and up 10% year to date.

TEA (Track Equivalent Album) sales were up 8% vs. last week, up 11% vs. same week last year and up 5% year to date.

Of course, we’ve been down so long, anything seems like up to us.
