Does it really?
ENDLESS STORY was good, as was GLAMOROUS SKY.. they were just VERY stable.
All that really matters is first week sales.. I don't think 200k is possible for female soloists, even for NANA. Maybe 100k for 2-3 weeks..

There's a preview snippet out for the NANA2 song that's by Mika...
It's a sort of ballad.. thing.
