Kuch to hua hai
Kuch ho gaya hai
Kuch to hua hai
Kuch ho gaya hai


Kuch to hua hai
Kuch ho gaya hai
Do chaar din se lagta hai jaise
Sab kuch alag hai
Sab kuch naya hai
Kuch to hua hai
Kuch ho gaya hai


Cheezein mein rakh ke
Bhool jaati hoon
Bekhayaali mein gungunati hoon
Ab akele mein muskuraati hoon
Badli hui si meri ada hai
Kuch to hua hai
Kuch ho gaya hai


Pighla pighla hai dil mera jab se
Achcha rehta hain mood bhi tab se
Haske milta hoon aaj kal sab se
Khush ho gaya hai jo bhi mila hai
Kuch to hua hai
Kuch ho gaya hai


Rang chamkilay saaare lagte hai
Raah mein bhikre tare lagte hai
Phool ab zyaada pyaare lagte hai
Mehki hui si jaisi hawa hai
Kuch to hua hai
Kuch ho gaya hai


Dhyaan ab apna zyaada rakhta hoon
Sochta hoon main kaise lagta hoon
Aaina ho to dekh leta hoon
Kaise yeh chehra aisa khila hai
Kuch to hua hai
Kuch ho gaya hai


Yeh nasha jisme dono rehte hai
Yeh lehar jisme dono behte hai
Ho na ho isko pyaar kehte hai
Pyaar mila to
Dil kho gaya hai
Kuch to hua hai
Kuch ho gaya hai.
