Between Selena's 3 best selling singles, which are Who Says, Love Song and Narurally, she has sold over (estimated)
5,600,000 digital downloads. Impressive I might say.
These would be the estimated sales for each of Selena's singles:
Falling Down - 400k
Naturally - 1.8m
Round and Round - 650k
A Year Without Rain - 700k
Who Says - 1.8m
Love Song - 2.1m
Hit the Lights - 300k
The total of her single sales would be over
7,650,000 downloads.
Now, if you add the sales of Tell Me Something I Don't Know (700k) and Magic (400k) the total of her sales would be
8,850,000.
* Remember, these are estimated numbers. Nothing official.
But tbh I haven't listened to this song in YEARS. I completely forgot about it. 
Like Crush or As A Blonde for example. 
SelenitaStan & Soma... 
Y'all can choke on one. Her giggle right after the bridge>>>> 
'Nuff said.
