As for the song itself ...
It divorced here the spirits. Some find it is complete garbage, others say the song is very catchy and the dancing well.
I think you have to listen to first, then the song is quite ok, but nothing special.
Since, however, was respected in this season for the first time only to the voices of girls, the song is probably more than inappropriate, since the votes were extremely processed. That's not uncommon in Electro music and it need not be necessarily bad, but you can not hear at all, who now actually sings, not even when Meike which has otherwise always get heard, I think.
I think a ballad would better fit as the first single, because the first single is nunmal very important if you do not want to end up like the winner of last year ...
Conclusion: Good cast, solid song - I would give 2 1/2 stars rounded up, these are just three.
