I was sick of copying and pasting yum codes to get people free downloads on Bandcamp, so I put some buttons on moon musiq's site to add the codes automatically. Add all of our stuff for free if you dig it:
http://moonmusiq.com/#releasesInstead of saying "hey, go to
moonmusiq.bandcamp.com/yum and type in 'n015-e666' blah blah blah", you can just add the code to the URL, eg
moonmusiq.bandcamp.com/yum?code=n015-e666. The "Add to your collection" buttons randomly add a code to the end of /yum and redirect to that URL when clicked.
