Personally, I didn't have a problem with the song, per se.I questioned the song choice for the singer. There's a few ways to go with such a song. The MM version would have probably been the best choice. And the Soft Cell version could be the right choice for another singer. To me? Her version sounded more like the mix of the song that Rihanna uses. And that's just not Rock Star.
What I've liked best on RS in the past is when someone takes a song like this that everybody thinks they know and puts a new spin on it. Like JD did last year with "California Dreamin'" or Marty did with "Hit Me, Baby, One More Time."
That would have impressed me.
