Yeah I know, what a shocker!
Ever since the Grammy Awards, there's been a lot of chatter about Lady Gaga grabbing the melody from somewhere; From where and whom, was up for grabs. Recently more has hit the net about Lady Gaga hacking her song Born This Way, but this time from the French singer/songwriter Mylène Farmer's 1986 hit, Libertine.
Someone posted a mashup comparison on YouTube. You be the judge.
This is a pretty obscure artists/song, at least in this country. I suspect if we look a little deeper at her other songs, it'll turn out the majority of them were rehashed from, I would guess, 1980s Euro-Pop.
