GUILTY was an extremely dark album, so in a way, it isn't exactly "mainstream" either.
Of course, I won't disregard NEXT LEVEL to be extremely mainstream either.. so yeah.
Well, it's quite obvious that in recent years, solo female acts' sales have been on the down.
I mean, it's just like Ayu is losing much popularity as we know... so at least for me, I wouldn't be expecting stellar sales.
Though it was really disappointing cos I expected NEXT LEVEL to like beat GUILTY due to the success of Days/GREEN and to a certain extent, Rule/Sparkle.
