It's getting to the point where her shtick is actually taking attention AWAY from her music and not adding to it. When I said she's better than that, I mean in the sense that she has the chops and the songwriting skills to be taken seriously as a musician, and right now she isn't being taken seriously by a lot of people because of antics like these.
Follow that route, and you end up like KISS. Everybody can tell you what they look like, but most people can't name more than 1 or 2 of their songs, if that.
There's a balance to it. Right now, she isn't actively promoting anything.
She's beginning to build the hype for the next record she releases and she wants to remain in the limelight in the interim. But that's not a good move. The thing to do is to disappear for a while and then come back with a bang. If you're always visible between records, it's tougher to have an massive impact when you return.
If she continues this way she will burn out very quickly. And there's a million examples of people who have done exactly the same thing. It's the easy method (especially in this day and age) but it's not the smart method.
