知足是幸福 - Contentment is happiness

This song describes the difficulties of life people usually face. But the real meaning is to tell us that contentment can bring happiness. It's also a very nice song. The video which is in cartoon style is also nice.

The World is A Big Family - 世界是個大家庭 - (music video)

Here's another song by the Pureland Music singer of Singapore, Ke Pei Lei (柯佩磊). It's really a nice song which tells us to pray for the peace of the world. There is also Roman Text on the video, so you can sing along.

佛陀的愛 - The Love of the Buddha

This is a nice song sung and created by Singaporean Buddhist. The song is in Mandarin. When searching for one of the singer (柯佩磊 - ke pei lei), I found a version uploaded to Youtube which has Roman Text, so it's easier for those who don't really understand Chinese to learn how to sing the song.
