What is striking here the extremely strange pronunciation of some words of Jogl. The German language is so rich in sibilant and glottal stops and in productions in the music industry attention is naturally paid to these sounds as possible "compatible" convey (who wants to know more: take singing lessons!). But what has happened here too: Sharp ß be transformed to säulsenden S. Of a K is a G, and so on. Jogl is Austrian and clearly it shows how the debate (Federal) German consumers has been adjusted (similar happened indeed with Christina Stürmer only is there far more compatible) - However, one shot here out over the target, it looks artificial and fake.
Furthermore, the voice is much too strong interspersed with chorus, tw. a flanger effect was apparently used. So what I know only for guitars, and not for singing. Technically therefore extremely weak. Too bad.
