Force Download .Mp3 file from different server

Yes, it is possible. You can attach the remote URL to your package.

I tried it, but when I click on download button it opens in new page..

Uncheck the “Open in Browser” option from the Basic settings page. That should do the trick.

Already did it still facing the same problem..

When the file is in a remote server or attached as an URL, wpdm can’t control its download behavior. You need to configure the download behavior where you hosted the file originally.
