The Hudson Public Library is offering members a chance to download three free songs for their iPod, cellphone, computer, or MP3 player each week. To access the music, go to www.hudsonpubliclibrary.com, and click on the Freegal link. From there, residents can search for specific tunes, request specific downloads, and download three songs for free. Once downloaded, the site’s counter resets and a new download will be available the following Monday. The service is for library card-holders whose library accounts are in good standing.
