Playing files from directory where new files are constantly added

I have directory where I save mp3 files (single mp3 file for one song) from internet radio. Initially this directory is empty or contain few, e.g. five files. I start mocp and play first song, then quit mocp. The internet radio streaming continue, thus, when 5th song is played, there are allready more files, e.g. 11, but mocp stop playing after fifth file, even if there are 11 files now.

Is there any way how to make mocp "refreshing" directory content after each song, so it can play freshly added files?

$ mocp --version
