世界はそれを愛と呼ぶんだぜ － サンボマスター

This is just the chorus, but this song is awesome. The last song in the new Ouendan game, and one of Sambo Master's best. This is definitely going in the karaoke list from now on too. This one is just on what I hear, not the actual lyrics, so it's entirely possible I'm completely wrong again, but I'm giving it a shot.

昨日のあなたがうそだというなら
昨日の景色を捨ちまうだけだ
新しい意味繋ぐのは
新しい君と僕なのさ
僕はなぜか確かめ合う
世界じゃそれを愛と呼ぶんだぜ
心の声を繋ぐのが
これほど怖いものだとは
君と僕が声を合わす
今までの過去なんて
なかったかのように
歌い出すんだ！

If you say the you from yesterday was a lie,
You throw away our entire background.
But if you attach a new meaning to it,
You have a new You and Me.
Why do I stay with you like this?
The world calls this love.
Bringing the voices of our hearts together
Is as scary as
Bringing your voice together with mine.
As if I am throwing away our entire past
I am singing now!
