Speaking of album sales... I am so looking forward to Duets!! I don't think it'll be a huge smash but I think it'll be a respectable audience number for a summer show. I was reading an article by the Hollywood Reporter that was discussing how much judges' sales rise. I think Kelly's catalog will see a nice spike, not only will she be on tv every week, but she'll be singing with her contestants every week! All of her fan request covers have been discussed all over the internet, so I can only imagine the press she's gonna get duetting every week! I don't want to get my hopes too high, but I think this will help her albums.
Here's the article I read:
