Google Play Music.
I've heard they sell my data, which is why I give them as little as possible. But the products are still very useful to me so I don't consider them junk.Oh.
I wouldn't know.
But it's still junk because it's Google. They sell your data.
I use my own library and a $12/yr Subsonic account to stream music from my server to all of my devices. For iPad and iPhone, I use the iSub app. For PowerPC Macs, I use jamstash.com within a TFF Box. Spotify on PPC will be missed, but I have alternatives
I looked into that. Sounds interesting. Even can run from a RaspberryPie.
I only don't know what machine to put to work as an server. My ideal candidate would be a broken MBP from 2007 as headless server but I think it wouldn't even boot with the broken graphic's chip.
