Hi,
i've notice an important bug but i could determine the cause..
i modified the ls_script according to wiki.sourcefabric in this way

## default = amplify(id="silence_src", 0.00001, noise())
## default = rewrite_metadata([("artist","Airtime"), ("title", "offline")], default)
## ignore(output.dummy(default, fallible=true))

music = playlist(reload = 100, "/var/www/owncloud/data/niculin/files/random") #random playlist
music = skip_blank(threshold=-50.,length=3., music)
jingles = playlist(reload = 100, "/var/www/radio/jingles")
auto = rotate(weights = [1, 4],[jingles, music])
default = auto

all seems to work but if i listen to the radio i noticed that every song is repeating with the same order every 30 minutes or 10 minutes.. but in the log of icecast there is not repetition..
I've noticed that when there is a repetition the listeners count is reseted..

with scheduled show or live show instead i haven't problems..

The problem happened either with the 2.2.1 or 2.3 airtime version..
these are the pastebin of the logs of icecast and liquidsoap (i attach in this post, just in case)

sorry for the "wall of text" but i think that is an important bug!
