The second single from SDN48, "Ai, Chuseyo" debuted at #1 on it's first day on the Oricon charts, selling 50,604 copies!
Unfortunately, it then dropped to #6 today, with an estimate (meaning, not a final number) of ~5,000 sales. orz
Of course, there are plenty of reasons to explain that drop.
First, as you should all be aware, Japan is still trying to recover from the earthquake that hit on March 11th, and buying CDs is probably the last thing on most people's minds right now.
Additionally, when the release was postponed from March 23rd to April 6th, that didn't stop it from being released onto Japanese iTunes. So, many people who might have gone to buy a physical copy could have decided to download it from iTunes instead. Of course, that's good since they still get the money, but it's bad since it won't show up on Oricon's charts. But with power outages, disrupted lines of transit, and etc, we can't really blame people for choosing to get it the easier way, can we?
Still, it doesn't matter if they sell 1 copy or 1 million copies. What does matter is that we support them as their fans.
