Definitely succeeded, but I'm not so sure if it could be considered a hit at this point. Yeah, it sold like a million copies its first week, but it was heavily frontloaded. It has one successful single while most other pop girls recently have had at least 2.
I say moderate success. If Bey gets some more promo it could become a sure hit, and it will be a hit if she releases Blow.
Its sudden release is iconic tho.
