For change of mood:

Gum gaye saare shahenshah,
ek huzoor baaki hai,
udd gaya saara nasha,
tera suroor baaki hai,
bik gaye mulk-o-siyasat,
tera nishan baaki hai,
teri aakhon se mein pi loon,
bas itni jaan baaki hai,
tu ek baar laut ke aaja,
ki itni aa.ns baaki hai,
tere hothon ko mein chakh loon,
bas itni saa.ns baaki hai.

-Akash
