I put the pitch 2 semitones up (and one octave down), checked a few parts that weren't right, proposed another title, added Metatags.
But the polyphony needs to be checked by a melody expert: It's mostly the Toto-melody now, even in parts where the singers (or one of them) deviate from it. But I think, as it is now, Ultrastar-users can sing the well known Toto-melody.
