Alright everyone, apparently Roogle will only sing Japanese songs, so I want him to sing a Japanese translation of the song 'Yeah' by Usher (I'm guessing that would mean it would be called 'Hai'). But what we need are the Japanese lyrics for it - so since we all know there are a fair few Japanese enthusiasts in these forums, can someone help me get these lyrics?
