ARIANA VS. DRAKE AND BLAKE

It's looking like a battle for #1 on both the HITS SPS and album charts this week, as debuting Republic siren Ariana Grande faces off against labelmate Drake for SPS supremacy, while dueling with Warner Music Nashville's Blake Shelton for the top album spot. Here's how it looks at the moment:

Ariana Grande (Republic) 150-160k SPS /120-130k albums
Drake (YMCMB/Republic) 150-160k SPS/55k-60k albums
Blake Shelton (Warner Music Nashville) 135-140k SPS/120-130k albums

How will it all shake out? Will the diminutive diva prevail, or will it be a Drakey Blakey chart week? These numbers will likely change in the coming days. Stay tuned for updates.
