I too could only sing in English four years ago. Lahore has an underground scene of very talented rock musicians, but they're stuck in the same problem. A lot of people heard it, but it's still a very small segment. It has a lot more depth. A lot of rock poetry is very direct.
Subcontinental people concentrate on the melody.
That, in some way, is the focus. No matter what you play augmented chords, minor-major they couldn't give a damn. They listen to the vocal line or the rhythms. Very well it comes in the experimental thing. In that way, poetry is a hindrance.
