I also cannot understand how watching videos in any way equates to album streams. I've tried to read and understand the explanation posted, but even that says video viewing is now about 6% of music consumed. Um okay, but isn't that still a small enough percentage that surely it can just be applied to singles?!
When they say videos, I assume they mean anything posted on YouTube etc, so if it's an official album tracklisting (with lyrics or some such playing as a video) that makes more sense as I suppose it's no different to streaming on Spotify.
But how you match up proper video plays for actual singles to album sales...I can't even process it. God why is everything so confusing
