Eurovision song contest 2012 winner accused of plagiarism!

Judging by the comments around the web Swedish Eurovision 2012 winner Loreen is accused for plagiarism. Her song "Euphoria" is a copy-paste of the song "Stole my Heart" from the English-Irish band  One Direction. Even before the contest this song was bashed by the critics that in some parts sounds just like Rihanna`s - "We Found Love" or even Katy Perry - "Fireworks".
However most similar song to Euphoria is Stole My Heart. See for yourself
