Changed exception to Exception to catch any errors that occur. Stops error with NameError when Spotify first opens up
Added basic OptionParser with Add and Change options
After realizing that OptionParser is depreciated, switch to argparse (again) and kept same arguments. In process of merging spotify_control and spotify_info.
Fixed --control functionality
Added modifier argument for character that seperates displays. Put display items in dictionary
Made d_values.keys() default values in display agrument. Catch NameError exceptions
Updated README, help argument, zsh file
