There is no English part of that song. There is apparently a separate English-language version of it, though, which is what you posted.
The lyrics go
Sometimes it seems Aditi
That somebody in your life
Is all there is to be
Sometimes it happens Aditi
That that someone goes away
And it feels like a bad dream
Oh when this happens how can you hold back those tears
How can you keep them in
And how can you try to believe
That everything’s gonna be OK
Sometimes it seems all that’s left in life is sadness
And there’s nothing that can make you smile again
A “cover” is a re-recording of a song by another artist. When AnalogSignal said it sounds like an English cover of Kabhi Kabhi Aditi Zindagi, he meant it sounds like somebody took that song and did an English version of it. I have to agree. The song sounds the same and the Hindi song even has “everything’s gonna be okay” in English if you listen carefully.
Thank you Jimmy, it was really kind of you to respond such quickly.
The last two lines are really tough, I really can’t get …
Oh, even when I typed some words in the song like " to hold back those tears" or very surprisingly by typing this long part " and how can you try to believe that everything’s gonna be OK" [ because this part was so obvious to me ] , but I couldn’t find the lyrics on the web.
BTW, Jimmy you just listened and jotted them down or got the lyrics from somewhere.
