I've listened the pronunciation of the word "hangover" on Cambridge dictionary (https://dictionary.cambridge.org/dictionary/english-chinese-simplified/hangover), both UK and US.

I am aware that g is pronounced as /ŋ/ here and I really didn't catch the phonetic sound "g" in there.

Nevertheless, I actually heard a few of people pronounce "g" in "hangover", like the "g" in "game".

So, should "g" in "hangover" be pronounced or silent?

Here is an example (https://youtu.be/_nRtCVJIToA?t=307) of a Canadian accent.
