As someone who loves pop music and believes to know a thing or two about the music business and entertainment...
I highly doubt big labels pay online services to receive (fake) views/likes/comments. IMHO, it's too risky and not even needed.
Artists, public relations managers and labels have other sources of traffic. More legit ones. Fans and real people who are interested.
Not saying they're not spending money. They do, in all kinds of ads and as an investment. But in a lot of cases, they're not paying a dime.
They have free promo in media like magazines, radio stations, on TV, website articles, YT interviews etc. So, try to think wider. Much wider.
