Question about song with long fade out + short station id + crossfade operator

[ArvyRogerio]

A question I always had about Liquidsoap but never managed to resolve is how to overlay songs using the crossfade operator in a specific case, when the current song has a very slow fade out and we apply a "station id" smaller than the fade out of the previous song. If I do a crossfade in this situation, the "station id" plays completely but the "next song" only plays when the "previous song" ends completely, causing some gap. My intention, in this case, it would realize that the "second" was also finished and play the "third" (next).

Below is a sketch in case I couldn't explain it well.

I even thought about controlling by myself, if I control the cue out positions myself, not using the crossfade operator. But I don't know if my idea is logic, to avoid wasting time for nothing. Something like:

radio = add(id="radio_add",[track1,track2,track3,track4])

and I would control where to insert the audio (1->2->3->4->1->2...) keeping each track blank when not used. I know it's hard work, but I don't need fade, just to overlap each audio.

Any thoughts or comments on this? Thank you very much.

Dismiss, I found a way to fix this using cue_cut AND crossfade together.
