[ashthespy]

As a first step – this is how simple it can be!

1. Edit the list to add the icon as a url

# Freshly added fav
volumio@volumio:~$ jq < /data/favourites/radio-favourites
[
  {
    "service": "webradio",
    "uri": "http://opml.radiotime.com/Tune.ashx?id=s255597",
    "title": "80s80s Radio",
    "icon": "fa-microphone"
  }
]

# Add the right icon 
volumio@volumio:~$ jq '.[].icon="http://cdn-radiotime-logos.tunein.com/s255597q.png"' < /data/favourites/radio-favourites
[
  {
    "service": "webradio",
    "uri": "http://opml.radiotime.com/Tune.ashx?id=s255597",
    "title": "80s80s Radio",
    "icon": "http://cdn-radiotime-logos.tunein.com/s255597q.png"
  }
]
