Hello,
Looking for a song, only know the description of the music video.

Girl(singer) turns stereos alive and the stereos start to follow her around turn. Sort of a happier song if I remember correctly.

Has to be between 2000 and 2010

This is about as much as I can remember, please and thank you.

Sounds like swagger jagger by Cher Lloyd. That happens at the start of the music video hope this is what u looking for!

I just found it, it's These Words by Natasha Bedingfield!
