YouTube has introduced this major change

San Francisco: Online video giant YouTube is introducing a major change to its music chart system after discovering that artists and labels were using growth hacks to inflate how many people were watching their videos.
YouTube is no longer counting “advertising views” when it comes to the company calculating its music charts. Instead, ranking for top-watched music videos will be based on organic plays, The Verge quoted a new blog-post as saying on Friday.
“In an effort to provide more transparency to the industry and align with the policies of official charting companies such as Billboard and Nielsen, we are no longer counting paid advertising views on YouTube in the YouTube Music Charts calculation. Artists will now be ranked based on view counts from organic plays,” the company wrote in a blog-post.
