I really love their song new ''Potential Breakup Song'' ^_^ which is one of their songs in their Insomniatic album...I also love the Music video of the song ^___^

I own their first album, "Into The Rush". I think it's really a strong Pop/Rock album, and the girls have loads of talent too!

I think "Potential Break Up Song" is an okay song, but I'm not crazy about it. They totally changed their style in that song.. it's like weird techno pop stuff..? lol, I don't know. I don't have their new album yet, so I don't know if their style is completely changed.
