Well, I mean, no shade, but Rihanna does the once a year album. It worked for her for about 6 years. Why can't Gaga do it?
Plus, if Gaga's done with the era, and she wants to move on (as it's clear that she does) I think she should move on.
People can take the overexposed comments from the radio stations how they want (it was true when they said it), but I haven't even heard Gaga on the radio. Maybe once a week, while driving randomly I hear, "The Edge of Glory," but that's it.
People haven't forgotten her, no, but if she released a good dance song that's fresh yet meshing with the current trend she'll have no problem being successful. And from what I can suspect, it will be.
