How to stream to old Sony via QNAP ?

[Koriolan]

Hello to everyone,
I found MinimServer and that forum while trying to force my old Sony CMT MX 700 NI to stream the one exact IR Station.

The Sony has built-in WiFi and was able to use Internet Radio until Sony cancelled the service.
But its able to stream files and playlist form my home NAS QNAP, so I try to surpass the limits of that device
The only way to control it is IR Remote, it has no app avaliable.

My first question - it is possible to make it working in any way ?

I have just installed Minimserver on QNAP, my music collection as well as playlists are accesible. MP3 only, no .flac but...
I also installed app on PC and added MinimStreamer
I have read carefully the guide and as I created the mp3u file

#EXTM3U
#EXTINF:-1,[RMS] Radio Nowy Swiat

BUT - second question is- WHERE TO SAVE IT ?
in QNAP Multimedia cataloque ? somewhere else ?

Thats the problem to solve
