Handling with Lists:
    * jamendo_dl.sh will create a tempoary copy of the file and deletes the finished lines, so you can continue your downloads.
    * After all downloads are finished, the copy will be removed.
    * If you are using --tag, a file (named like the tag) will be created, conaining all IDs."
