So I did this with my new Stream Deck XL:
(cameo by Mort the Beagle.)
It’s a little clearer from the config app:
As you probably guessed, each button opens a web page on Relay.fm’s website.
Clearly, Relay cannot add any more shows!
(Also, in my order “The Pen Addict” comes after “Parallel” and before “Playing For Fun” … unlike on Relay’s “Shows” page, where it shows up after “Rocket” and before “Thoroughly Considered”.)
I have another button on my main profile which will launch the livestream in VLC and record it in Audio Hijack but this was fun to put together.
If you’re silly enough to want this too, you can download my Relay.fm.streamDeckProfile.
