Browsers are really bad at downloading multiple files at once, so we collect our albums together in .zip archives first. Simply double-click the .zip file and it should expand into a folder full of tasty, tasty MP3s. If something else happens, you may have accidentally changed the default program for .zip files to something that can't actually open them. Try right-clicking on the .zip file and selecting "Expand" or "Open with..." and then choosing an unarchiving utility (we recommend 7zip for Windows or the built-in "Archive Utility" for MacOSX).
The Loudr direct store was closed in 2017, and music purchased from Loudr will not be available forever. We highly recommend that you download your music and keep it in a safe place!
