The correct name of Céline Dion is with e-acute.
She used the variant with ‘é’ in her early days (in the 1980’s) at her albums.
Starting from the 1990’s she used just “Celine Dion”, with a ordinary ‘e’.
Also on her website the ordinary ‘e’ is used.
Strictly following the rules the artist name in MusicBrainz.org should be changed to the variant with ‘e’ and album credits (starting with the 1990’s) should be changed.
I’m sure, this will to pass the voting process.
