I have been listening to this song since quite a few days. It is one of the better songs that have come from the movie Roy. The lyrics are really great and has a deep soulful connection.
Mujhse hi aaj mujhko mila de
Dekhoon aadaton mein, tu hai ki nahi
Har saans se pooch ke bataa de
Inke faaslon mein, tu hai ki nahi (x2)
Main aas-paas tere aur mere paas..
Tu hai ki nahi
Tu hai ki nahi
Tu hai ki nahi
Tu hai ki nahi…
Daudte hain khwaab jinpe rasta woh tu lage
Neend se jo aankh ka hai waasta woh tu lage
Tu badalta waqt koi khushnuma sa pal mera
Tu woh lamha jo na thehre aane waala kal mera
Main aas-paas tere aur mere paas..
Tu hai ki nahin
Tu hai ki nahin
Tu hai ke nahin
Tu hai ki nahin…
In labon pe jo hansi hai inki tu hi hai wajah
Bin tere me kuch nahi hun mera hona bewajah
Dhoop teri na pade to dhundhla sa main lagun
Aake saanse de mujhe tu taaki zinda me rahun
Main aas-paas tere aur mere paas…
Tu hai ki nahi
Tu hai ki nahi
Tu hai ki nahi
Tu hai ki nahi… (x2)
