It works in theory, but in practice, execution is often flawed.
However, with the tv ad coming out, and the BTWB going European (that's not a new style of bikini trim) it has a higher chance of success.
Except everyone has the song and the non-German speak goes on too much for the casuals.
The better idea would be to run this idea once her album leaks (probably a week before release), select favourite song, then have GGD flood all social networks with it. TEOG was a bit surprising, I don't know if it's happened before where an artist has been almost forced to to release it. That CAN happen with a new album, but not BTW, I'm afraid, unless she were to do tv promo and stuff to get the casuals interested, or duet it or something.
So yeah. It'd work for the next one, but beware, it could lead to another Judas/Edge screwup.
