Band Camp Album Extractor

This python script extracts all of the songs for a bandcamp album download.

pip install bandcamp_extract

From github repo

To install this package simply run

pip install .

in the root of this package

Setup

After installation the extractor's binary is called bcextr.

Breaking change (0.2.0): bcextr is now a command group. What used to be bcextr <zip> is now bcextr extract <zip>.

bcextr extract works standalone with no setup. The bcextr api commands pull albums directly from your Bandcamp collection, which requires a one-time login first.

Bandcamp has no username/password API, so this reuses the same session cookie your browser already has after you log in on bandcamp.com.

1. Get your Bandcamp username

This is the name in the URL of your own collection page: https://bandcamp.com/<username>. You can find it in the account menu on bandcamp.com, or from the URL after clicking "Collection".

2. Get your identity cookie

1. Log in to bandcamp.com in your browser.
2. Open developer tools (F12, or Cmd+Opt+I on macOS).
3. Go to the Application tab in Chrome/Edge (Storage tab in Firefox), then Cookies → https://bandcamp.com in the left sidebar.
4. Find the row named identity and copy its Value column. It's a long opaque string — copy the whole thing.

This cookie is a live login credential for your account: don't share it, paste it into chat tools, or commit it anywhere. bcextr only stores it locally in ~/.config/bcextr/session.json (readable only by you).

3. Log in with bcextr

bcextr api login

You'll be prompted for your Bandcamp username and the cookie value from the steps above.

If your cookie later expires, just re-run bcextr api login with a fresh value.

Usage

bcextr extract

Extract a zip you already downloaded:

bcextr extract ~/Downloads/album.zip --pattern ~/Music/{artist}/{album}/{title}

Default pattern if not provided is: ./{artist}/{album}/{title}

bcextr api list / bcextr api choose

List your collection:

bcextr api list

Pick albums and extract them straight to your library:

bcextr api choose --pattern ~/Music/{albumartist}/{album}/{title} --format flac

This opens an fzf multi-select over your collection, downloads each chosen album in the requested format, and runs it through the same extract/rename logic as bcextr extract.

--format accepts one of mp3-320, mp3-v0, flac, aac-hi, vorbis, alac, wav, aiff-lossless. If omitted, you'll get a format picker (applied to the whole batch) instead.

This relies on Bandcamp's unofficial, undocumented collection API and may break if Bandcamp changes it.

bcextr mv

Reorganize an existing folder of music (searched recursively, however deep the files are nested) into a pattern-based structure:

bcextr mv ~/Music --pattern ~/New_Music/{albumartist}/{album}/{title}

Pattern substitution

The pattern substitution will substitute any parameter it gets in tinytag The file extension will also be added to the end of the pattern when moving the song to it's destination

tag.album         # album as string
tag.albumartist   # album artist as string
tag.artist        # artist name as string
tag.audio_offset  # number of bytes before audio data begins
tag.bitrate       # bitrate in kBits/s
tag.comment       # file comment as string
tag.composer      # composer as string 
tag.disc          # disc number
tag.disc_total    # the total number of discs
tag.duration      # duration of the song in seconds
tag.filesize      # file size in bytes
tag.genre         # genre as string
tag.samplerate    # samples per second
tag.title         # title of the song
tag.track         # track number as string
tag.track_total   # total number of tracks as string
tag.year          # year or data as string

It is important to note that any files that are not music (in the zip, or in the source folder for bcextr mv) are not moved to the destination folder.
