groovy song...: chorus: "...revolution.."

Hello,
Today, I´ve heard a song in a german H&M store. Very groovy, I was kinda dancing along to it with my daughter . It even sounds like children singing : Chorus: "ohohohoh..it´s time for revolution" (repeated). Guess it´s even in the charts, but I´ve missed it for some reason. Can you help me out? Thanks a lot!

it might even be "evolution" instead of "revolution", though that doesn´t make much sense...but who knows.

Nobody there who knows this song..?

It might be Revolution by The Veronicas

chorus goes:

Hold on tight, I am, Im a revolution

They are young girls singing it so look up on youtube.
