The Wonder Girls' "Tell Me" and Big Mama's "Betrayal" have taken the online world by storm, that's for sure. But there is one big difference in how they've won over fans. The Wonder Girls' "Tell Me" is number one when it comes to streaming and ringtone rankings. But when it comes to the internal ring category, Big Mama has pushed the Wonder Girls out of the spotlight and stolen number 1 for three weeks in a row. One expert says that when it comes to internal rings, people opt for songs that show talent and mostly ballads, instead of tracks that are generally popular and show a conservative mentality.
