^Koda Kumi also released 12 singles for 12 weeks
That's Avex marketing.
But really, Bonnie's releases are a bit more sporadic than most artists.
She doesn't always follow the typical single-single-single-album formula.
She's released singles that haven't been on any albums (
Surprise!,
Inu to Tsuki,
Daisyi, etc), and some albums have only had one single (usually released
just before the album).
None of Bonnie's singles have come in cd+dvd format. I think that's a relatively new thing.
By Bonnie's usual release schedule, I always got the impression that she finished writting an album, and then decided which songs she would use as singles - not the other way around like a lot of artists.
Hey, we're just lucky that we're getting any kind of PV DVD release from Bonnie
