So, I'm *really* confused about purchasing the music from the radio stations. Not the soundtrack, but the music from the radio stations from the base game and Phantom Liberty. What's the official (if one exists) place to buy the music from the base game and expansion?

As far as I know, the only place where to buy that is the official CD Projekt Red store. It is only available on vinyl, and it's still a pre-order thus far.

Link for the US official store: https://gear.cdprojektred.com/

I'm a bit confused too - aren't all of the different radio station soundtracks available on Youtube?

...And it's smooth sailing to download them?
