Holy moly! I just discovered that throughout that big, lovely, wonderful page of Downloads… none of the links worked! It turns out that if you enter an offsite URL into the appropriate download field in the Download Manager plugin, you must also click the plus sign icon next to that field to submit it. I had mistakenly assumed that filling out the field and clicking the Publish button would automatically submit it. Doh!
So now you can download to your heart’s content! All of the songs are available in uncompressed AIFF format. Interested in other formats? Well, SoundCloud permits downloads, so you can grab MP3 files from soundcloud.com/transistorsandwich.
