You know what else would boost sales? Making this song the A-side instead:
Whereas I merely liked "Lullaby Game", I'm hooked on the B-side. It's got a funkier house/electronic feel and lots of energy and attitude, sounding a bit like it came from the Sonic CD soundtrack.

It's clear that Tsunku can still make exciting songs for this group, but those songs need to be pushed to the forefront instead of tucked away like this.
Speaking of sales,
it's official...this single sold more in its first week than the previous single did in its entire run! Great to see an upswing, though I wonder how much was helped by the buzz surrounding the triple graduation. Hopefully this momentum can carry on into the new year and new lineup.
