Starting on October 28th, YouTube Red will let folks in the US start watching all the movie trailers, phone reviews, music videos, epic fails, adorable babies, cat clips, and rants they've been consuming for years, sans ads. In exchange, viewers hand over $9.99 a month instead, or $15 if they have a Play Music family plan.

Unless, it turns out, you're one of the early Play Music subscribers. Google is sending out emails to folks who hopped on board in the early summer of 2013 to inform them that when they are transferred to YouTube Red, they will get to keep their discounted $7.99 rate. Google is also tossing in a free month.

Here's the text of the email in full.

We’re happy to let you know that your Music Key beta will become YouTube Red on October 28. To say thanks for your help with Music Key, we’re transferring your subscription from the Music Key beta to YouTube Red and giving you a free month of YouTube Red starting on October 28. There’s no action needed from you. And if you choose to keep YouTube Red after November 28, you'll receive the discounted price of $7.99 per month for as long as you’re a member. YouTube Red gives you the same benefits as Music Key - ad-free videos, save offline and background play - across all of YouTube whenever you log in to YouTube or a YouTube app. We learned during the beta that people wanted Music Key features to work with all YouTube videos, not just music. But that wasn’t all. We also learned that music fans like you wanted a unique home for YouTube’s catalog of songs and artists. That’s why we’re super excited to also announce the YouTube Music app (coming soon). YouTube Music is designed to make discovering, watching and listening to music easier than ever. We hope you love your free trial membership of YouTube Red. Your first billing date will be 12/1/15. And you can always manage or cancel your membership in your settings.
