(CNN) -- Note to the Grammys: You may not want to seat Sharon Osbourne anywhere near U2 at the next awards show. "The Talk" co-host and wife of rocker Ozzy Osbourne went on a Twitter rant about the group's recent free release of its new album on iTunes. "U2 you are business moguls not musicians anymore," she tweeted. "No wonder you have to give your mediocre music away for free cause no one wants to buy it." Ouch. In a deal that cost Apple a reported $100 million -- including fees to U2 and a marketing campaign for the album -- the Irish rockers released their first album in five years,"Songs of Innocence," through iTunes to every subscriber to the Apple service. The group announced the freebie at the Cupertino, Califonia, press conference for the new iPhone 6.
