When comparing the semis, it currently seems as if semi 2 is the hardest to qualify from. No matter how I look at it, Denmark looks like a borderline qualifier. Which makes it all the more problematic that Saba's vocals are so shaky. When only a few votes are going to make a big difference, Denmark will need a strong vocal performance, and I doubt she can deliver it. She may be trying to improve her voice this spring, but that could easily be cancelled out by her nervousness when she hits the stage.
Perhaps DR will try to add an even louder backing track - there seems to be no limit to the amount of backing tracks allowed at Eurovision these days.
