LegalSounds have got a great feature on their site to help you download music. This is their 'Download Manager'. The manager is designed to help make downloading music a whole lot easier. The manager looks just like the site, but you can pause downloads, queue downloads and access all your account info and details without needing to go to the website.
You can download the manager from the site. For full instructions on how to download and install the manager, check out this: How To: LegalSounds Download Manager.
