Singapore National Song

或許是Tommy才疏學淺，這個Title translate in Chinese 應該是新加坡國歌？
And i surely think the MV above isn't the Singapore National Anthem,is there anything wrong?
OK,i love this song named this is home,and put it on my blog to share with you!
Singapore is a beautiful land i like best,a Harmony Social,and she got the NO.1 in
the city of most suitable for urban living in Asia 2007(also NO.1 in the world)!and NO.2---NO.10 is Kobe(神戶)Japan,Tokyo(東京)Japan,Osaka(大阪)Japan,Hk,Macau,ChineseTaipei,Bangkok(曼谷) Thailand, Kuala Lumpur（吉隆坡）Malaysia,George Town（喬治城）Malaysia.
So,where is the Chinese mainland city?i feel so sad,my dear friend,do you think China is harmonized?
