G                           D
Kabhi mujhe lagey ke jaise, saara hi yeh jahaan hai jaage

Jo hai aur nahin bhi hai, yeh fiza ghata hawa bahaarein
G           D
Tujhe kare ishaare ya
Am           D
Kaise kahun, kahani main inki


Chorus:
Em
Jo bhi main, kehna chahoon
G               Em
Barbaad karein, alfaz mere, alfaz mere

Em
Oo yeah yeah oo ..
