My two cents:
Lukas disappointed tonight. Oh, I like his stage presence and all. But after hearing him open up last week, hearing him growl his way through half of "Hero" was painful. I kept thinking how great that song might have sounded if he had just kept his throat relaxed instead of growling.
I didn't like Dilana's singing either. Maybe it's different, hearing it in person versus hearing it over my non-stereo tv, because I thought her lower registers were weak and she should have sung in a higher key.
I really like Magni, but he's probably too nice for SN. I don't see him pulling the kind of antics on stage that I think SN might want in a front man.
