But they didn't need promo for PRA and SAIKI neither, they both sold very well on their own, it was just that promo gave them a boost which always has been very big (I only remember Adele who profits from promo that much).
Sorry is not that different to their previous singles so it's surprising that it falls off that much.
Or people are still full by Sexy And I Know Ir and need to get hunger again...
But you are right, danbarj, the goal should be to get Platinum for the album though this of course takes longer for them as a singles artist than for artists mainly selling albums
