thanks for this info - I was not aware - it does not work for my six - as two are here and two west of town and two south of town.. some fosters.. so not same household.. but glad this is a thing.
The other day to prevent a young one from replaying the same soundtrack over and over via youtube - (bandwidth repeatedly counting against and lots of ads for the same repeated songs oh my) - I just popped over to amazon and bought the album and popped it onto a usb stick for them.
I picked up a couple of gift cards for their bday this week - one of them was a google play card - then I remembered G killed the music section of the play store, so I put it back and got an amazon card instead.
that premium would be a great deal if we had one more in the household here. we've got three chromecasts - two with the google tv - but not the gtv plan - sheesh the ads via youtube with that are a drain, and I wonder about the compression for music - but they still use them for convenience and the other things like discovery+ which is affordable.
Oh if only they would plex-like into a win7 box on the network and pull my collection of mp3s.
Maybe all this is going in a good direction. Fingers crossed.
