Ok, this is an educated guess.
These were the best and latest statistics i could get.
In September 2006, Steve Jobs announced that iTunes owned 88% of the legal music download market.
iTunes had 10,152,284 downloads a day on average, from 6 to 8 Billion downloads.
- so like it went from 6 to 8 billion downloads in like 200 days (10M x 200 = 2Billion)
A report released by the IFPI in 2009, stated that 95% of music downloads are illegal.
- so iTunes has 88% of this 5%
If we put that together......... 88% of 5%
The 5% of all music downloads is 11,536,686 a day
so the illegal market is....
230,733,727 illegal music downloads a day.... amazing huh? 230 Million a day.
So per minute thats........ 160,232 songs per minute
