I'm a barbie girl in a barbie world. Best song ever!
Yes! The popular song by Aqua, the Danish dance-pop group!
Even The Beatles can't compete with Aqua and Barbie Girl. 
It debuted and peaked at number 7 on the US Billboard Hot 100 on September 6, 1997. 
I remember when it came out. The CD was in my player 24/7.
It also became the subject of a controversial lawsuit "Mattel v. MCA Records."
I did not know that interesting. What was the lawsuit about?
Mattel sued because the lyrics of the song are about Barbie and Ken, dolls that are made by Mattel.
