This is one of my favourite songs by Zee Avi. She has an awesome voice! Some of you might have known her because she is winning fame internationally. Anyway, here's some info about her.
Zee Avi is a Malaysian singer-songwriter, guitarist and ukulele player. She was born in Miri, Sarawak, Malaysia. She moved to Kuala Lumpur when she was 12. She studied fashion design at American Intercontinental University in London.
Her single "Bitter Heart" was first to become available on the US iTunes store, and her full self-titled debut album was released on May 19, 2009, co-produced by Bushfire Records and Ian Montone's Monotone Records.
