Doubletwist says that the album is by an unknown artist.

[AC Question]

Hey, for some reason under the album it says 'Unknown artist' and the cover is just the grey music note symbol. For example, I have a few Eminem albums on doubletwist. All of my albums are correctly placed in the artist folder 'Eminem'. The album 'The Marshall Mathers LP 2' is there and all of the songs on that album have the correct artist listed and the album artwork there. But, when I click on 'Eminem' and view all of the albums, it just shows the music note icon, says 'The Marshall Mathers LP 2', and below it says 'Unknown artist'. I am using double twist on a Samsung Galaxy S2.
