As if Lil Wayne's "Rebirth" wasn't shaping up as planned before, a pre-order blunder has seriously marred its release even moreso today. Amazon accidentally shipped around 500 copies of the oft-delayed album to pre-order customers this week -- even though the release date was pushed back to February.

 Universal Motown and Cash Money Records have claimed they needed more setup time on the set; speculation also indicates that the famous hip-hop artist had yet to settle on a final tracklist after initial impressions of leaked tracks and first single "Prom Queen" came back mixed. The retailer nor the label had no comment to Billboard when the error was discovered.

The release date for the rock-and-rap experiment has moved at least six times this year, most recently from Dec. 22 to Feb. 1. The new single "On Fire" has only recently began building in sales through digital retailers.

Not that we condone it, but: Look for a leak of the Amazon version on an Internet near you.

All this, and on the day that Lil Wayne got more bad news: it was announced that he's due in court on Feb. 9 for sentencing in his gun possession conviction. He faces a year in jail as part of his plea bargain.
