I only heard him sing one song, I'm not saying he's a bad singer but just that it's not his job, it really borders on ridiculous that a comedian/mc can become a singer. You never see this sort of stuff going down in proper music industries.
HK music is basically all the same, I don't know why they bother sometimes, who even buys that stuff? I think it's what they call the karaoke genre, songs that are easy to sing and cater to that audience.
