Google on Tuesday announced YouTube Music, YouTube Music Premium, and YouTube Premium on Thursday — a dramatic change to its current music and video offerings.

Here's basically what's happening: It's getting rid of YouTube Red and splitting that into new services. YouTube Red, if you're unfamiliar, was a $9.99 monthly plan that offered an ad-free YouTube experience that included music. Customers who currently pay for YouTube Red will get the new YouTube Premium service at the same price they currently pay.
