JUST FOR FUN
From INI you will notice KINI in the lyrics
Kini = now; but it is different from sekarang because
1. Saya buat sekarang but you cannot say *saya buat kini.
2. Kini saya belajar bahasa Melayu and also Sekarang saya belajar bahasa Melayu
So Kini is a now-state of time while Sekarang is now-state of time and currently.
Sekarang has an additional immediacy meaning
compared to Kini which is this time.
