Shows download links for the preview files on bandcamp albums
No, the script shows the mp3 files that bandcamp offers as a preview. Currently that's only 128. To offer other options, the script would have to re-compress the mp3 files, which is much easier done with a real program than in a script in Firefox.
Not too important question, but just wondering
Any chance of getting options smaller than 128 quality?
(I'm new to scripts so this is not a criticism of your great script, great job!)
