I am streaming , how can I play music when provider goes down.

I stream Amazon Ultra HD. Music I like I download to my LG V40 phone that's used strictly as a player. I use it I walk or can stream to my system through BT AptX or wired. No internet required. This is a great way to explore music because you can download without having to buy and it stays there while you keep the streaming service. I do also have a Bluesound node for system streaming with gigabit fiber internet. 

And people wonder why I have 500 CDs on a SSD.  :)

Hello To all ,I just have a fanless computer  running Roon,qobuz and separate dac 

i will purchase whatever is needed , I am just building a reference digital system

it bugs me to be crippled ,every time spectrum goes out 

when I have 1Terabytes of Flac files on a Solid state drive ,

much appreciated with any all help !!

I only use Flac files no fm tuner, or phones I want to be able to access my Flac files 

how to access them ,and how to play files and pick music to play ,

when my service provider is down ?

iwas even thinking in the future like my friend to spend $500 for the Tesla starling setup then pay the $100+ for music and Audio , at a later date .

Roon 2.0 requires an active Internet connection at all times to work. And obviously Qobuz does as well. If your Internet connection goes down, use different software to access and play the locally stored music.
