bandcamp-downloader
Download your Bandcamp collection using this python script.
It requires you to have a browser with a logged in session of bandcamp open. Cookies from the browser will be used to authenticate with Bandcamp.
Supported browsers are the same as in browser_cookie3: Chrome, Chromium, Firefox, Brave, Opera, and Edge
Albums will be downloaded into their zip files and singles will just be plain files. Downloads are organized by Artist name. Already existing files of the same name will have their file sizes checked against what it should be, and if they are the same, the download will be skipped, otherwise it will be over-written. You can use the --force
flag to always overwrite existing files.
Downloads will happen in parallel, by default using a pool of 5 threads. You can configure how many threads to use with the --parallel-downloads
/-p
flag. After each download a thread will wait 1 second before trying the next download. This is to try and not overwhelm (and be rejected by) the bandcamp servers. This can be configured with the --wait-after-download
flag.
If a download should fail because of an HTTP/network error, it will be retried again after a short wait. By default a file download will be attempted at most 5 times. This can be configured with the --max-download-attempts
flag. By default, a failed download will wait 5 seconds before trying again. This can be configured by the --retry-wait
flag.
By default, files are downloaded in mp3-320 format, but that can be changed with the --format
/-f
flag.
Known Issues
Failure to read cookies on Windows for Chrome/Chromium/Brave
This is a known issue with the browser-cookie3 module. I've submitted a PR to fix it here. In the meantime, firefox should still work fine, and I have created a branch here with a patched browser_cookie3 module that should work.
DBUS_SESSION_BUS_ADDRESS
error
Running the script on WSL crashes with a This is seems to be a WSL issue. The browser_cookie3 module tries to get a secret from your keyring via dbus, but WSL may not have dbus installed, or may not have it set up as expected. As such, you may see the following error:
secretstorage.exceptions.SecretServiceNotAvailableException: Environment variable DBUS_SESSION_BUS_ADDRESS is unset
Please either check your WSL dbus installation/configuration, or run the script nativity on windows.

Notes
If you have a logged in session in the browser, have used the --browser
/-b
flag correctly, and still are being told that the script isn't finding any albums, check out the page for browser_cookie3, you might need to do some configuring in your browser to make the cookies available to the script.
If you are downloading your collection in multiple formats, the script can't tell if an already downloaded zip file is the same format or not, and will happily overwrite it. So make sure to use different directories for different formats, either by running the script somewhere else or by supplying directories to the --directory
/-d
flag.
