देखो, ओ दीवानों, तुम ये काम न करो, राम का नाम बदनाम न करो

Simple philosophy built into lilting music. The exhortation to 'know God' and 'conquer the mind by studying the [Bhagavad] Gita' is deceptively simple, lyrics-wise.

कांची रे, कांची रे, प्रीत मेरी साँची

Lovers argue why each should not leave the other ... The true meaning cannot be conveyed by a drab translation ... you have to experience the song in all its melody and semantics. I didn't discover until recently that the raag ♫भूपाली is behind this melody.

दो लफ़्ज़ों की है, दिल की कहानी

"The tale of [two] hearts, is made of [only] two words ... love or youth."

If you interpret love or youth to mean true love or infatuation, you can see some justification in this simplified interpretation. It is said that Asha Bhonsle herself regards this song as one of her best renditions.

भीगी भीगी रातों में ...

Playfulness induced by song and dance in the rain, in a manner that only Bollywood can come up with.
