याद किया दिल ने, कहाँ हो तुम?

In this song, the female lover expresses her feeling thus: ...

... मतलबी जहां, मेहरबान हो तुम

Don't we all value selfless behavior, romance or otherwise?

जाने वो कैसे लोग थे जिनके प्यार को प्यार मिला

A heartbroken individual sings:

When I wished only for [beautiful] buds, I got a garland of thorns ... 

Life may not always produce such extremes, but Bollywood can cook up beautiful songs. Why not?
