When I heard the song, I did not know who is the interpreter. But after a few seconds I thought, "Well, that sounds to by Tom What's he doing in Turkish for Beginners.?". And when I looked later, he was there actually.
The song is really good and beautiful, very dynamic and in spite of everything not messed up or exaggerated. I like Tom Felton's voice - and especially its extreme accent - very very good and I hope we will hear more from him in the future.
In the scene of the song fits very well, it was therefore a very good choice.
