Thanks ron for your Answer.
I found another solution to solve my problem but it’s not very useful : I have my mt-daapd server on which i can play songs and i use iTLU (iTunes Library Update) to update my iTunes Library with a Samba Directory on my NAS.
So, every new song must be added to this library… but it’s working …
I will try to search another soft and perhaps this function would be implement …
Regards
