Allmusic review not showing up on new releases

I think you’ll find it’s now quite simple:

Where does AllMusic get its information?

The album, artist and song information on AllMusic comes from our data provider, Rovi. Rovi provides us with written content like reviews and biographies, tagged metadata like Genres, Styles, Moods, Themes and Similar Artists, as well as information about credits, album covers, sound clips, music videos and a ton of other good stuff. Providing your product to Rovi is the best way to get your information on AllMusic.

My product information is appearing on the AllMusic website, but not on some of the e-commerce sites that Rovi supplies data to. Can you fix that?

It is up to each Rovi licensee to determine what products they present on their sites. Any questions you have about the presentation of your product on other sites should be directed to the owners of those sites.
