What phrase or words do you notice ayu frequently using?

[AYUmyQUEEN]

Many choruses start with bokutachi, boku, or bokura: voyage, marionette, immature, bye bye darling, tell all. I'm sure I'm missing some. Obviously this isn't anything major since they just mean we/me and those are words that will naturally show up a lot, but I just thought it was interesting before I learned any Japanese and was trying to remember the melody to some of her songs years and years ago.
