You just needed to submit your most listened. Yes, the Binding Lights is the most listened on Spotify but I don't think it's the most listened of all time because there are still 70% (afaict) people who don't use streaming or YouTube to listen music. The most listened song imo is the 'Hanuman Chalisa' because it's played everyday by millions of people in India for it's a religious song. You can see the stats for this devotional song on youtube and be surprised. 4.1 Billion views for a devotional song!!
