Today’s the day. Every fall you can measure Target’s clout in the music business by whom the retailer lands for its fall managers meeting at Target Center.

The long, long meeting is still in progress but thus far Super Bowl-bound Bruno Mars, the Band Perry and Luke Bryan have entertained.

We’re betting Justin Timberlake will be the day’s biggie. After all, his “20/20 Experience” has been a big sales experience for Target and Volume 2 of that disc is coming this fall. We’ll try to keep you updated.
