Courtney Love has launched a vicious tirade on Madonna’s singing skills via a blog on Myspace. Kurt Cobain’s widow labeled the Material Girl a weak, irrelevant musician. “Madonna is a great businesswoman, but come on, she is weak as an artist and we all know it.” “I like Madge, but as a relevant musician, it’s a joke she’s singing from such a calculating, thought-out place all the time, it’s never from her gut or heart or intuition.”
