Linguistically-speaking, Finnish is not Scandinavian but Uralic, thereby related to Estonian, Hungarian, and various minority languages of Finland, Sweden, and Russia (Sami, Udmurt, Mari, etc). No clear genetic relationship has been established with the Turkic languages (sorry, Scamandrius), though the urheimat suggested by the name "Uralic" might cause some confusion in that regard (the Urals do run through parts of Kazakhstan and other areas where Turkic languages are spoken). Culturally of course it may be another, more complicated matter, as Alpo points out.
On to the topic at hand: I am so glad to be firmly on the path to joining a church where this kind of thing is not tolerated or encouraged. Call me crazy, but I really do think that there ought to be maintained in the minds and hearts of the people a strict division between what is allowed in a liturgical context and what is not. Luckily for me, Egyptians (and Syrians, Ethiopians, etc.) are generally not keen on heavy metal music, though theoretically it could be some other thing (I would be just as unhappy to find "Chaabi" showing up in church).
