The code is well-structured and easy to read. It uses Deno to handle command line arguments,
and it makes use of the spotify.ts module for playing and pausing track playback. The args
variable is used to store the command line arguments passed to the script, and the command
variable is used to determine which action should be taken based on the first argument.

There are a few things that could be improved:

1. Use a more robust way of handling command line arguments. Instead of using Deno.args, you
   could use a library like commander.js or yargs to parse and validate the arguments passed to
   the script. This would make it easier to add more commands in the future, as well as handle
   errors and provide better help messages.
2. Use a consistent naming convention for variables and functions. In this code, some variables
   are named with camelCase (e.g. args and command), while others are named with PascalCase
   (e.g. pausePlayback). It's best to stick to one convention throughout the codebase.
3. Add error handling for cases where no arguments are passed or an invalid command is provided.
   For example, you could print a helpful message and exit the script if the user doesn't provide
   any arguments or if they pass an invalid command.
4. Consider using a more modular approach to your code. Instead of having all the functionality
   in one file (i.e. cli.ts), consider breaking it up into smaller, more focused modules that can
   be easily imported and used in other parts of your application. This would make it easier to
   maintain and update your code over time.
5. Consider using a dependency injection container to manage dependencies between modules.
   Instead of importing the spotify.ts module directly in the cli.ts, you could use a dependency
   injection container to provide the necessary dependencies to the cli.ts. This would make it
   easier to test and maintain your code, as well as make it easier to add or remove functionality
   from your application.
