There is a function in mobile qq, which is to enter the song name in the chat box and then share the whole song automatically.

I'll search the specific rules of this function again … but it's already a bit of a doorway! First of all, it's useless to just announce the title of the song! It's no use adding the singer's name, such as entering "Confession Balloon"! But enter "Jay Chou confession balloon" and a sign will appear! Enter "Jay Chou" and nothing will be displayed! But enter "singer's name+sung" and the logo will appear on the right! It's all his songs! This logo has nothing to do with whether the chat is hot or not! I will send a logo to anyone! But sending it to the other party didn't show it … that is to say, only I can see the logo … so far I haven't seen anyone else have this function! To sum up, this function may be related to whether it is QQ svip … it may be a member privilege …
