Streaming has grown, yes, but only to fill the gap in the market that the decline in digital sales created. Blank Space more than doubling Stay's streams cannot be explained simply by the growth in streaming between 2013 and 2015 - Blank Space is simply the more popular song.
The growth is clear seeing as 4 videos reach 1B this year
"Blank Space" is the bigger hit for now, but "Stay" has had incredible longevity and is probably Rihanna's most recurrently played song on the radio right now. Adult Contemporary/HAC plays it all the time as if it was a current hit. I haven't really heard "Blank Space" in recent months, even after all of it's domination when it was #1.
