If they're on your device how could you not have heard of them? I'm sure the answer will be obvious when you give it.
They are probably not 'on' my device. My device is my phone. I use Google music. A small amount of my library is stuff I uploaded myself many years ago which is where the Moby song came from I'm guessing. However most of it is in/came from the cloud. It's too easy to click 'add to my library' on google music if I hear five seconds of a song I like. It's gotten to the point where I don't know what's in my library or how big it is. I'm also not sure what it means. If I can listen to anything available on google music anytime, what difference does it make if it's in "my library"? On this note, it is surely one of the biggest flukes of all time that the first track that came up out of potentially thousands was Mama.
There's a toggle to play only the stuff downloaded to my device so maybe I should do that for this thread.
