It all started with this song, Fade to Grey by Visage:
Visage – Fade to Grey
Then Kelly Osbourne got sued for using it without credit for her song, One Word:
Kelly Osbourne – One Word
Then this Italian guy took Kelly’s song and made another hit from it, without giving credit to either of the above songs:
Tiziano Fierro – Stop Dimentica
I like them all.
