Song: 一起走過的日子/The Days We Passed Together (Rough Translation)
It's really hard to choose one song out of all of Andy Lau's music. This song is timeless and really shows his talent as a singer. His voice is expressive, strong and pleasant to the ears. I always think of his voice as the embodiment of true manhood--it's not about being loud, having a very deep voice or singing songs about your physical/sexual prowess. Andy Lau's singing has an innate strength and masculinity that comes through so well that it really makes other male pop singers seem like boys rather than men in comparison.
Valen Hsu - 許茹芸 (Xǔ Rú Yún)
Song: 独角戏/Du Jiao Xi/One Role Play (Rough Translation)
I remember the first time that I heard this song was in a restaurant. I actually liked it so much that I asked the waitress for the name of the song. Although I'm not sure if I've ever heard it before, the song was hauntingly familiar. It's slow but definitely not mellow--there is a tension in the song that really pushes it forward, and Valen Hsu's smooth vocals are perfect! Also note that she held some insanely long phrases in there.
Jane Zhang - 张靓颖 (Zhāng Liàngyǐng)
Song: 畫心/Hua Xin/Painted Heart (Rough Translation)
Jane Zhang's most famous song must be 天下無雙 from the Condor Heroes. Not as many people know about this song from the movie 畫皮 (Painted Skin). It's beautiful and equally impressive--note the high notes in the bridge!
