if you enable more verbose logs (set("log.level",5) in the script), you
should be able to see if the metadata are seen to the operator.
Here is log example of a transition where the metadata got lost:

I'm wondering wether some runtime limitation, like CPU power, could make
liquidsoap behave in a hurry at the end/begining of track, and possibly loose
some
metadata.
My server is a dedicated one so I have load average: 0.00, 0.01, 0.00

Another consequence of not using smart_crossfade is some strange noice
at the end/beginning of mp3 files. What could that be?
Smart_crossfade can be expensive in terms of CPU power.
Also, mp3 audio format is not very handy to compute in advance the end of a
track.
Since smart_crossfade makes use of the metadata of the old and new song,
if you enable more verbose logs (set("log.level",5) in the script), you
should
be able to see if the metadata are seen to the operator.
