 Well if we assume that since:
- the album has sold 6.5M+ (I'd say close to 6.6-6.7 though since it has sold 300k in the US alone since Aug 2013 

) 
- the singles, at a moderate estimate, are 55M 

- the era (incl most videos) is around 3B 

- Spotify streams are over 600M (I think I calculated it ages ago but can't find it and cbs calculating again) 

...14-15M (TEA/SEA) is a fair guesstimate
