"hikki people..." such a weird phrase LOL.. you can simply say hikki fans
.
That is because hikki didn't have several consecutive no. 1s to make a streak.
Automatic wasn't no. 1,
Movin' on was,
First Love wasn't, then 4 singles no. 1, broken by
FINAL DISTANCE, then another five no. 1 singles, broken when
Passion was released. Since then Toshiba never places hikki in a safe week for single release.
Let's see ayu... ok, from Free & Easy --> talkin' 2 myself, there are 17 consecutive no. 1s (correct me if i'm wrong). That is a long no. 1 streak among female artists. If she didn't release Daybreak then probly had 6 more no.1 consecutive singles (from M to Dearest... A song is born doesn't count cuz it's a duet). This is why avex (and probly to ayu herself) wanna save this streak as long as possible.
If you dun believe that, then look at KinKi Kids, and more specially, B'z. I'm sure placing KAT-TUN battling with them will definitely kill their streaks (average debut week for KAT-TUN was ~350K), as both KK and B'z selling less than 200K on the first week.
I have a feeling tho that ayu's no. 1 streak will be broken in about 2 yrs or so.. 100K on the first week is pretty much normal now. If ayu can still manage to sell over 100K on the first week, avex can manage to get a safe week for her... If her singles starting selling like crap (e.g., talkin' 2 myself), her streak will be broken at anytime..
