DOWNLOAD THIS: The iTunes album Top 10 nicely sets up next week's likely battle for #1, between MJ and The Black Keys, and the following week's likely Top Two, Coldplay and Brantley Gilbert. Otherwise, Turnover Tuesday could be called Transient Tuesday, as an array of new releases have their moment in the sun (and Demi Lovato finds $4.99 a very nice price). On the singles side, a slew of Voice contenders make some noise, occasioning the irony of John Legend being one spot behind a contestant's cover of his song. Look for a lot of these newbies to clear out in the near future, while Ariana and Iggy continue their tete-a-tete and Columbia's trinity shines on. (5/13p)
