The most streamed song in the first half of 2013 was streamed 438,450,000 times

The song was, somewhat unsurprisingly, the massively over meme-ified "Harlem Shake" by Baauer. In comparison, and as a clear example of the increasing reach and strength of streaming, the song most played on radio, Bruno Mars' "When I Was Your Man," was spun a mere 392,000 times.
