As a fan or Rihanna, I won't be buying the album because it only has three extra songs on it, which I have already downloaded and I have the original album from last year, It's a little annoying when bands/artists decide a couple of months down the line to re-release the album as special edition with more songs.
Most of the time this kind of thing happens to me when I buy an album. Usher will do it next, not like I brought his album,I download that, not that great anyway, but my point is it seems like it's best to wait
