^I think the quality of the songs would affect the sales, especially for an artist with declining popularity like ayu. Only strong ayu fans will buy it the moment it comes out. Casual listeners are going to want to know whether its good or not first before buying.
The covers aren't really buyer-friendly
, if I wasn't an ayu fan I would NOT buy NEXT LEVEL after seeing the covers. Plus ayu is experimenting with a style of music that people aren't used to. Perhaps if sales remain steady like they are now for the next few weeks, maybe its a sign that people are coming around.
