Last year I put together a Halloween playlist and tried, where possible, to link to the tracks on Bandcamp. At the time, Bandcamp did not offer a Playlist feature; they've since added one, but it's limited to mobile only (and I've found, not a lot of use there either).
(I also provided a Spotify playlist. Not all of the tracks in the playlist were available on Spotify, or Bandcamp.)
Since then I discovered an independent service bndcmpr which lets you build and share playlists from tracks hosted on Bandcamp.
I'm not sure whether it will have longevity, but for now at least, I've ported my Halloween 2022 playlist over to bndcmpr. You can find it here: https://bndcmpr.co/cae6814a, or with any luck, embedded below (if you are reading this post on an aggregation site, or newsreader, it's less likely that this will appear):
I'm overdue cutting the next playlist, theme TBA. Stay tuned.
