I just took a look at michael wong guang liang, I can find him, but no songs. 

Can you share a link or screenshot?

Hi @wAh !

I checked the artist you mentioned.
His profile exists, but there is nothing in the Discography.

https://www.deezer.com/en/artist/10394518

I found his Albums.

I see that all songs are grey.
This means that they are not available in my country and therefore I cannot listen to them.
They are probably not available in your country either.

Here is link : Song/Artist/Album isn't on Deezer - What happens if I can't find the music I want?
