Hindi songs of Emotional Impact - nostalgic, favorites etc

[Shakthiprabha.]

SP, idha paarunga -
"janam janam ka saath hai, nibhane ko sau sau baar humne janam liye"
But idhu konjam older than 70's-nu ninaikkaren.
Innoru Mukesh paattu irukku similar to the Milan song in a rebirth theme film - but I doubt if you are referring to that one - it is very obscure.

illai plum, its none of those....
It had a typical rdburman type...peppy, on toes. (late 70z or early 80z)

and words used were janmom or yug or sadhiyon saal etc

many tried to spot the song but in vain.
I have a vague feeling, may be I am forgeting to place it back

My mind makes me picture the song sung somewhere in a beach or may be mountains (quieter places , uninhabited may be)

One strong memory has it that a particular word gets REPEATED.

like 'sou sou'
or 'janam janam' ka
or 'sadhiyon sadhiyon' mein

etc
