The chorus is the catchiest part, and I think they will add a little oomph to the final version chorus. The verses are perfect the way they are, the build up to the chorus is fun and energetic, just needs a little spectacle here and there. The only thing that really needs a good change up is the bridge. It's too generic, just repeating 'be my ooh la la' over and over. It needs more pizazz right there. Overall, this will do well because the general public will eat this up. Most people hated S&S before, and it grew on most. It smashed! Ooh La La will be a grower, but it can be a top ten hit for sure!
