Platinum records are special awards given to artists who have achieved great things with their music.
The Recording Industry Association of America (RIAA) started awarding gold records in 1958 as a reward for selling 500,000 physical singles or albums.
Then, in 1976, the platinum record was introduced, which required one million physical copies to be sold.
But with the rise of the digital age, fewer people buy physical albums, so the RIAA had to come up with a way to continue rewarding hit songs.
So now, 150 streams on sites such as YouTube and Spotify count as one sale.
