Via Firefox native downloader I can download hundreds of mp3 without ip ban. If JD2 can't find any other way then Reconnect is the best solution. But as I said once error starts, JD2 changes all download address (which encoured the error) as album address so after changing my IP, continue to download is not possible.
BTW Even 1 downloads per time with 1 chunks brings ip ban with JD2.
