well, let me share my opinion about Hong Kong singers. First of all, I think male singers' songs are better, because most of their song melodies are excellent. Few years ago, I loved Eason Chan because of his soft voice. But currently he does not sing very often and he only gets a very few new songs. Currently, I love Leo Koo and Deep Ng. Their songs are sweet sounding.
For the foreign singers, I just know a little bit about them. However, I usually listen to songs sung by Westlife, "Michael learns to rock" etc. But in particular I love Gareth Gates. He always sings by heart, I know. I love his "ANYONE OF US" most.
And here I would like to introduce some old, romantic songs that I like:
1) Trademark- Only Love
2) Richard Marx- Right Here Waiting
3) Michael Learns to rock- That's why you go away
4) Gareth Gates- Anyone of Us
Finally, I would like to mention that we should not love a singer just becuase of his/her fashionable look.
