On Friday, the music industry is going to have to make some hard choices about which stars are worth watching on their YouTube channels.
The Top 100 Artist Chart is a ranking of the top 100 artists on YouTube with videos from January to December of this year.
The Top 200 artists are a look at the 200 most popular videos of the year.
The chart includes more than 20 million video views from January through December.
The artists on that list have been making a name for themselves over the past few years, including Rihanna, Justin Bieber, Justin Timberlake and Lady Gaga.
In February, Katy Perry made headlines when she announced she was leaving music altogether, leaving behind her popular social media accounts.
She was also reportedly upset with her own fans.
In the last year, several stars who are still very popular have left YouTube.
Katy Perry is the latest to leave the platform.
In October, Drake announced that he was retiring from music, citing health reasons.
In September, Madonna said that she was retiring after 20 years in the business.
The music industry, however, seems to be having trouble keeping track of which celebrities are truly successful.
There is an increasing number of stars who have made millions, but are still doing well on YouTube.
