(It is true and I am a surviving witness--coming from one wicked New Year's party--to the fact that dark and demented souls do exist that would violate a specimen as "Inta Umri" in the most torturously sacrilegious way by injecting it with a techno beat.)
LOL! I totally agree with you. My cousin thought he'd please me (since I love Oum Kalthoum) by making me listen to the techno "remix," and I did feel not only it violated her song, but I kinda felt violated by it too.
I will say though that despite her operatic "Ameen" at the end, most of the Lord's Prayer is preserved only with a higher tone of music. That's pretty much it. If you ever heard George Wassouf sing "Inta Omry" he sings it a lower tone, since his voice can't reach Oum Kalthoum's high tone. I'm a very bit advocate of "high toning" some of our Coptic hymns, with a strong voice like how Fr. David Bebawy sings them as I shared earlier.
I assumed that since Abir Nehme sang the "Lord's Prayer" at a Syriac Orthodox Church that she was Orthodox, but I may be wrong.
Here's one sung by a priest:http://www.youtube.com/watch?v=QqLZr11JhMM&feature=related
