I disagree. It's baseless to say that no one has Southernplaya at the top of their Outkast list, because you can't prove that. I think there are actually a lot of Outkast fans who have never heard Southernplaya and would be delighted to hear it for the first time on good wax.
I personally prefer VMP choosing the less *popular* album because it might be something I've never heard before and when I get it I'll find out I love it. It also puts the less popular album in the spotlight for people who may have heard it a couple times but tended to default towards the popular albums, which could lead to people re-listening to it and finding out they like it more than the popular album.
Strictly from a business standpoint, you can argue that choosing the more popular album is the better choice to make because it means more people will sign up and purchase the record, but ruins the spirit of the "club" part for me. I would much prefer a record club that isn't focused on selling out every single ROTM by choosing the real crowd pleasers every single month. At that point it loses a lot of the charm.
It's like a book club where you only get classic books in the mail each month. Yeah, they're generally great books, but I'm not really expanding my taste by delving into the real surface level of literature.
