Their record label have given this as the artist name when they included their work on Spotify, not much I can do about it. Besides, I want people to hear their music and care less about statistical correctness.
Clearly printed on "Ahenk" and "Ahenk 2" is "Derya Türkan & Murat Aydemir" -- why have people been voting against that version and for this incorrect one? Peculiar.
