Here’s a piece based on the mood and phrase "Bahut din hue hain dekhe tujhe mere yaar" — written as if it could be lyrics or a ringtone poem.

Bahut din hue hain dekhe tujhe mere yaar Ab teri yaadon ka hi sahara hai yaar Har subah teri hansi dhundti hai aankhein Har shaam tere bina adhoori si lagti hai Tera chehra, teri baatein Tham si gayi hain raatein Aa ja phir se milne zara Bahut din hue hain dekhe tujhe mere yaar (Instrumental hook — flute or whistle tune, 8 seconds loop)
