The letter is supposed to be private. No one should auction it. She was openly jealous and bitter of Whitney and Mariah.
From her Jan 1996 Spin magazine interview
Spin: Are you dissapointed that Time Warner jettisoned Interscope? Shouldn’t a company whose main product is artistic expression stand up for its artists?
Madonna: [Sighs] I’ve had several discussions with [Warner Music Group CEO] Michael Fuchs and said, look, I’m not a big fan of music that’s degrading to women or that promotes violence. I am offended by these things too. I’m offended by a movie like Showgirls. I still don’t think that the way to remedy the situation is to go around telling everybody what they can and can’t do.
I think Time Warner, or any of these big. corporate conglomerate entities, should encourage work that is morally uplifting. that counteracts all [the negative sluff]. I think when you’re fed a steady diet of crap, you come to expect it after a while. But art is not really a very important part of our culture any more. I was talking to k.d. lang about it last night. I don’t want to get into slagging off other artists, but we were talking about her record versus someone like Mariah Carey’s — and I think she’s a very talented singer — but we have to realize that the same country that acquitted O.J. is the same country that makes a complete piece of shit movie No.1, that buys Marian Carey records. It’s this homogeneity. But it’s got nothing to do with art.
From her 1995 NME interview
"pop is short for popular and to remain popular you can’t have a point of view or be outspoken. To remain popular you can’t go against the grain. Janis Joplin, at this time, in this world would not be a popular artist. Chrissie Hynde does not sell as many records as somebody like Mariah Carey. And that’s because Manah Carey and Whitney Houston don’t have a f**ing point of view.”
Whitney had one about you, didn’t she – she said that she’d kill her children if they turned out like you.
Madonna arches her brows coolly. “I’ve never heard either of them say anything horrible about me. But if they have, it’s completely transparent why. It would be based on jealousy of the fact that I have a point of view. I think that its an artist’s responsibility to have a point of view. Society takes its cue from popular art. People need something to look to, something to provoke them into questioning whether they completely hate something or completely love something. Perhaps somebody like Mariah Carey wishes she could make that happen. On the other hand,” she smiles nastily, “if you’re not terribly bright I suppose that you don’t really give a damn.”
