Yes, you could use a blank() source and set the switch to be insensitive to
track limits to it switches to the queue as soon as it is available:
silence = blank()
radio = fallback(track_sensitive=false, [ request.queue(), silence])

There used to be projects for this. Prolly some of those here:

You can annotate requests with metadata this way:
queue.push annotate:title="Title 1",artist="Artist 1":/path/to/file
Metadata are filtered for security reason. The list of accepted metadata
tags is set through this setting:
set("decoder.metadata.export",
["artist","title","album","genre","date","tracknumber",
"comment","track","year","dj"])

This can happen if for instance your server lacks CPU resources to
compute/encode the stream in real time.

That sounds like a fun project! Hope these clarifications help..
