Wrong tag! Respect the singer's wishes. Cheryl has decided her new stage name is Cheryl to avoid all the confusion. Here is an article about it: http://mirror.co.uk/3am/celebrity-news/cheryl-cole-drops-new-married-3956199
Also, all her releases (including the older albums) on Spotify have all been changed to [artist]Cheryl[/artist]. So we should update our tags.
