Well, it's official. As we helped to blow the whistle last week, Joni Mitchell is definitely the next signing for Starbucks' Hear Music label.

Hear Music will release Shine, Joni's first original album since 1998, on September 25.

Although this is a good move, seeing as how Joni Mitchell fans probably do spend at least 40 percent of their time at Starbucks, I'd still prefer that they sign Prince, for the spectacle alone.

But, Joni has worked with the label before, having put together a compilation of some of her favorite songs for Hear Music in 2005.

Shine is a 10-song album that includes an adaptation of a Rudyard Kipling poem and Mitchell says it's "as serious a work as I've ever done." The other nine are Joni Mitchell originals.

Paul McCartney, the label's first signing, has sold 447,000 copies of his debut on the label, Memory Almost Full. Forty-five percent of those sales were made in Starbucks stores.

Finally, I'm holding out for Prince, as the label is expected to sign one more artist this year and eight more next year. The AP reports that label execs are looking for a mixture of new and established artists. Right, because they really broke Antigone Rising into the mainstream.
