to many competitors for spotify
Gaana, Saavn, Youtube, Apple, Amazon, hungama, Jio, Wynk, but it only launched a yearish ago and nearly has all local music + excellent algorithm to find songs, so will not take time to catch up.
Facebook also uses whatsapp contacts to show pymk. I added someone on whatsapp whom I never met, but was dealing for business in different continent and was shown in facebook very next day. I was not surprised, but decided to stop using facebook soon.
