And I'll follow you follow you home is a metaphor for reaching orgasm
Like I've always said. The girl writes lyrics like an old Hollywood film. The sex is there, but its not shouting out at you. You've got to really listen to the sexual innuendos.
From the above video, if you watch/listen again, didn't you feel she's testing something? Most likely new rock songs. I will not feel surprised if she reveals some new music later. Didn't it happen before? Is it possible The Giver song? Rock song with Coldplay will be a dream come true. But testing with u2-styled SoG though?
