RIAA counts streaming as 100 streams = 1 purchase, so lets make some estimates.
Spotify: 8,402,630 (84,026)
YouTube/VEVO
music video: 33,646,864
lyric video: 530,169
audio: 2,216,560
total: 36,393,593 (363,936)
552,000 + 84,026 + 363,936 = 999,962
That would put Body Party at around 1 mil, but this is -
NOT- guaranteed because we can't tell if ALL of those streams are from the US.
However, I didn't add in numbers from MOG, Muve Music, Rdio, Rhapsody, Slacker, and Xbox Music so that would add more to the total.
(again, this is
NOT guaranteed [and I'm not too sure about how the RIAA streaming system works
])
