Prism, Teenage Dream, 21, X, a few other Drake albums, Title, In The Lonely Hour, and Pure Heroine off the top of my head
Also, I can't believe The Chainsmokers' EP has 1.7 billion streams.
Closer and Don't Let Me Down, their power. It also probably helps that they have three songs in the Today's Top Hits playlist though.
1B streams is barely an accomplishment anymore though. Any artist can get that with a few hits nowadays since streaming has become so big. 2B should be the new standard.
