या रब्बा ... प्यार है या सज़ा, आय मेरे दिल बता

Nice collage of stories of several heartbroken lovers.

माही वे

Elaborate description of a female by a male lover — तेरे गाल गुलाबी रब्बा रब्बा, चाल शराबी रब्बा रब्बा —
her response — बजे मन में हलके हलके शहनाई रे — and,
a mother's wish — खुशियाँ जितनी है सब ढूंढ ढूंढ के लाऊँ — all rolled into one song.

And, the lyricist is — drum roll — Javed Akhtar.

नूर-ऐ-खुदा

The poet brings out a recall of unhappy events, and a plea to God to produce justice, by the character in the film.

Other singers of this song are Shankar Mahadevan & Adnan Sami. (I could not fit these names in the Labels field). That Shankar Mahadevan has brought out a musical piece that sounds like an original Arabic singer's rendering, is a testament to the universal nature of music and, of course, to Shankar's musical abilities.

कल हो न हो

कभी अलविदा ना कहना -

The first few lines of this song are very perceptive of the lyricist in bringing out the feelings that may exist in the former lovers of a separation, or divorce, that is about to happen.
