An Instagram DM led to Aarzu, this year's breakout independent hit
Producer Noor and 18-year-old singer Khan met through an Instagram message, then wrote three songs in six hours in a Delhi hotel room. One became Aarzu, which has crossed 31 million streams and reached No. 4 on the Billboard India Songs chart on July 18. They have since released O Piya and recut Aarzu with Pakistani singer Asim Azhar.
