All instrumentals since then have been offshoots of songs on the album. I adore all of Rahman's instrumentals, esp. of late with Kaise Mujhe, Khwaja, Jashne Bahaar, Meherbaan......simpily out of this world, BUT, I miss his original theme music instrumentals like in 1947 earth, Lagaan theme, some tracks in Taal.
Rahman saab, please create more original instrumentals in your albums.
