In the real world, no one says they're EXCITED to hear what Katy has to put out besides her fans. They know the kind of music she makes, and there's always one of those songs on the radio. They'll love the music once she puts it out, but people don't actually get excited about an upcoming era of hers.
I'm not saying the GP loves GaGa, because a lot of them dislike her, but people do get genuinely excited to hear what she has to put out next, what crazy outfit she'll wear next, what stunt she'll pull on stage.
