We can add Sharon Osbourne to the list of people who weren't impressed by U2's decision to give away their new album, 'Songs of Innocence,' for free as part of a massive product launch promotion through Apple's iTunes store.

Osbourne ripped the band on Twitter, listing the reasons for her disdain in a series of tweets that started with the following pointed observation: "U2 you are business moguls not musicians anymore. No wonder you have to give your mediocre music away for free cause no one wants to buy it."

That's a silly thing to say, given that she's talking about one of the best-selling bands of the rock era -- and given that their last release, 2009's 'No Line on the Horizon,' sold five million copies worldwide during an era in which that's really nothing to sneeze at. But as Osbourne continued, it seemed clear that her beef is not with U2's lack of an audience, but her feeling that they're totally out of touch with reality.

"Guys nothing is for free, how much you making? PS, btw you are just a bunch of middle age political groupies," she added. "Whose political ass are we going to pull you out of today? Or are you front row at another tragic fashion show?"

But all that clueless middle-aged-rock-star stuff might pale in comparison with what drives it -- and what, in Osbourne's view, could delude otherwise sensible people into doing something she thinks is so foolish: ego. She ended her anti-'Songs of Innocence' screed with a tweet directed at the band, its label president and the store, writing, "Jimmy Iovine, iTunes, U2, you're a bunch of megalomaniacs. F--- YOU!"

You'll notice that none of Osbourne's tweets had much to do with the music, and it's worth pointing out that the new album's opening track, 'The Miracle (Of Joey Ramone),' has drawn praise from some of Ramone's survivors, including his brother Mickey Leigh.

Ramones drummer Marky Ramone said he thought Joey (who passed away in 2001) would have been "honored" by the song, while Leigh admitted he was blown away by the gesture. "I’m not sure grateful is the right word, but awestruck is a better description," he said. "It’s so beautiful. I loved it. It’s Bono’s interpretation and his spirit, but it also captures Joey’s spirit. He described my brother’s spirit well. I think he got just what Joey would have wanted out of it."
