Prince not a fan of Glee cover
Prince has hit out against covers of his songs - including Glee's version of his single Kiss.
The singer told the Guardian: "There's no other platform where you can do that.
"You can't go and do your own version of Harry Potter. Do you want to hear somebody else sing Kiss?"
In his interview, Prince also denied frequent rumours of an appearance at Glastonbury, claiming his name is being used to "sell the festival".
He said: "I've never spoken to anyone about doing that concert, ever."
But he was full of warm words for British star Adele.
"When she just comes on and sings with a piano player, no gimmicks, it's great."
