[Picaflor 7/4]

Wanted to be a little creative with the title....anyways.
I noticed this with Ayumi's songs a while ago. She's the only artist I know that fills her songs with empty singing so often. Half of her songs are filled with "woah woah woah woah" "no no no no no no" and "lalalalala". Can she not come up with something else to put there or at least not sing during those parts? I feel like she ran out of lyrics or something. I don't mind if she does it for a few songs, but the fact that almost every album has a few of those songs where she just fills in space with empty singing kinda annoys me. Could someone enlighten me as to why she does this so frequently?

Maybe I'm just looking into this a little too much.
