On-demand, video, online radio, whatever: this is who’s serving streaming music to the world right now.  The breakdown is based on the most updated, figures supplied by the companies themselves, then annualized and proportioned (methodology below).

…come geek out with me on methodology:

(1) YouTube Music Videos. Estimated 5 billion views per day WW; or 1.825 trillion/year.  Accustream iMedia Research estimates that 38.4 percent of that traffic is music videos (others peg it closer to 40 percent), you get 703 billion annualized.

(2) Pandora. At current rate of increase, Pandora will conservatively hit 14 billion listening hours in fiscal 2013 (ending March).  Assuming 12 songs per hour, that’s 168 billion.

(3) Spotify. Since enterting the US, Spotify reports 13 billion listens over the past year.  At roughly 25 percent of global listens, that’s 52 billion worldwide.

(4) VEVO. Estimated 90 percent overlap into YouTube; 4 billion views/month; 48 billion views worldwide.

(5) Rhapsody.Using the company’s reported 1 million subscriber total, assuming a higher per-daily play of 20 million from paying subs.  (total = 7 bln)

(6) Grooveshark. The Office of Technology Licensing at the University of Florida pegged the figure at 150 million per month in 2010 (we’ve seen this estimate elsewhere).  We inflated that to 200 million given some very noticeable growth since 2010, though in fairness, both Alex and Compete have shown considerable declines over the past year or so).

(7) WiMP. WiMP only offers cumulative streaming numbers, though its more regional service has 350,000 subscribers, or roughly 8.75 percent of Spotify’s.  Without normalizing for territory, we did a straight line.

(8) Rdio, MOG. Neither report numbers; reportedly quite low.
