As it was stated - Tsunku has been making H!P songs for 18 years, songs overally - for longer, even. Some of his songs weren't as great - but let's face it - expecting every his song to be great would be just stupid. When you're doing something for so long, you do experience things like writer's block or a burnout sometimes. And if you add the fact that you're responsible for a few idol group that has to realase a few singles a year to keep their popularity, I imagine that you may feel the pressure that makes you be like "alright, it's time to write another song" more often than "ah~! I'm so inspirated to write a new kick-ass song!"

And yet, I think that Tsunku managed to do it decently. Apparently he has a nature of a real musician.
