There's a couple of command line flags you can use with blitzloop - run blitzloop --help to see them. All of them can be overriden via one of two config files:

• /etc/blitzloop/blitzloop.conf
• $XDG_CONFIG_HOME/blitzloop/blitzloop.conf (generally ~/.config/blitzloop/blitzloop.conf)

See [this file][example.conf] for an example. You don't need a config file, if you're happy with defaults.

You can use blitzloop-single to quickly play a particular song. This is useful for song-testing, and when you're really desperate for a quick karaoke fix. You need to point blitzloop-single at a specific song.txt file. See blitzloop-single's help for more details.
