I always install python cli apps [pipx](https://pipx.pypa.io/stable/)
when I can

Manually download the two packages in question or download spotdl
manually. The issue is that bandcamp-downloader isn't asking for a
particular version of beautifulsoup and mutagen, but spotdl has a
dependency on particular versions of those packages.

Some general advice for working with python packages is:

1. Never modify the system installation of python
2. Use [virtual
environments](https://docs.python.org/3/library/venv.html) (or the
[conda equivalent](https://conda.io/projects/conda/en/latest/user-
guide/tasks/manage-environments.html#) if you're using conda) or
[containers](https://www.docker.com/) to separate dependencies for
projects.  [pipx](https://github.com/pypa/pipx) is a good alternative
for if you're installing a whole application via pip (as opposed to a
library you're using in your own project).

This particular error is happening because `bandcamp-downloader` has
`beautifulsoup4==4.11.1` as [a specific dependency
version](https://github.com/iheanyi/bandcamp-
dl/blob/master/requirements.txt#L3C1-L3C23) and spotdl and
syncedlyrics requires a newer version of beautifulsoup (i.e. a version
`>=4.12.2`).

If bandcamp-downloader and spotdl/syncedlyrics are part of separate
projects/could be separated into their own virtual environments or
installed with pipx, that would resolve this issue.  If that's not
possible, I've [seen people suggest](https://www.reddit.com/r/Python/c
omments/ua2a7k/how_do_you_manage_conflicting_packages_in_your/) that
these kinds of dependency conflicts can be resolved with poetry or
pip-tools, but I'm not familiar with the details.
