This song is the best so far on YouTube! The meaning/story of the song is "Christina" is loving a guy, But the guy dates many other girls but does not tell "Christina" about it, Then "Christina" saw her BF with another girl.
Even though the meaning is like that, I still LOVE it, The tune is great, Her voice is so nice (Damn I wish I had her voice!) and the music video is EPIC! I hope you listen to it too, I'm now memorizing the lyrics.
