Song choice for YG Entertainment 2nd round audition — rap or vocal?

Hi everyone! I’m preparing for a possible second-round audition for YG Entertainment, and I wanted to ask for advice about song choice.

My strongest skill is rap, but I can also sing and dance. For the second round, I want to choose a song that really shows my individuality, confidence, and stage presence instead of just copying a famous performance.

I wanted to ask:

For YG’s second round, is it better to perform rap only, or can I show both rap and vocals?

Should I choose a song by YG artists (like BLACKPINK, BIGBANG, CL, etc.) or a non-YG song that fits their style?

Is it better to perform an original rap or a rap part from an existing song?

How long should the performance usually be for the second round (for example, 30–60 seconds)?

What do judges focus on more in the second round: skill, confidence, tone, or overall performance energy?

I want to choose something that highlights my strengths and shows that I understand YG’s style, but also keeps my own color as an artist.

Any advice or experiences would be really helpful. Thank you so much!
