This is the best way to determine if your chorus and lyrics flow well together. Read your rap out loud or practice rapping it and pay attention to the content of the chorus and lyrics as well as the flow and structure of your rap. You may have practiced portions of your rap to the beat you have chosen, but you should perform the entire rap to the beat to listen to the connection of the lyrics to the music. You can also practice putting intonation in your voice to emphasize certain lyrics or the hook. After you have practiced your rap, you may find that it is just as you want it, but it's possible that it needs some tweaking to improve the flow, continuity, or cooperation of the lyrics to the beat. Edit your lyrics or beat as necessary so that you achieve your best rap. Music is created for others to hear, so why not try performing your rap in front of a small audience or a friend? You can then ask for suggestions or constructive criticism.

TL;DR in Indonesian:
Latih refrain yang sudah Anda buat dan cobalah memadukannya dengan keseluruhan lirik. Rapalkan lirik dengan irama yang sudah dipilih. Sempurnakan kualitas lagu Anda. Tampilkan karya Anda.
