For some Bandcamp albums (like this one), youtube-dl throws an error, although the album is playable on the page without issues. For most other Bandcamp URLs, everything works fine.

Thanks for the report. It's because that youtube-dl mistreat tracks without songs as real tracks. It will be fixed in the next version.
