What is the difference between 歌うが好き and 歌うことが好き? (also please explain what the meaning of こと is and how it changes the meaning of the sentence)

Hi, I have your answer.

Explanation:

歌うのが好き means, you like singing/to sing a song.

歌っているのが好き means, you like the state/situation which you are singing.

So, こと changes the state of which you are talking about the subject. (?) I could be wrong, but I think this is right. I hope it helps!
