Song from Rohan Rathore IIT-Gawahati

Ho Love of mine,
With a song and a whine,
You're harsh and divine,
like truths and a lie,
But the tale end is not here,
I have nothing to fear,
For my love is yell of giving and hold on,
In the bright emptiness,
In a room full of it,
Is the cruel mistress ho ho ho,
I feel the sunrise,
The nest all hollowness,
For i've the way to go not home,
And i feel so lonely yeaaahh,
There's a better placefrom this emptiness,
And i feel so lonely yeaaahh,
There's a better placefrom this emptiness,

Aaa aaa ....,

Tune mere jaana , Kabhi nhi jaana,
Ishque mera,Dard mera,
Tune mere jaana , Kabhi nhi jaana,
Ishque ...mera,Dard mera,
aashque tera , bheed me khoya rahta hai
jaane jahaaaaaaan,
poocho to itna kahta hai ,
"that i am sooo lonely yeahhhh".....
