# The list of options that are safe to change between songs on a
# playlist
# Each tuple has the following entries:
# 0. Option "key", like the one used in the options.OPTIONS dictionary
# 1. A dictionary of option values that require special displaying:
#    the key is the value of the option and the value is a string that
#    should be shown on the song info screen if that option is
#    selected.  If there is no key for a particular option, the string
#    that is displayed for that value in the option menu is used.
#    E.g. for the "jumps" option, value 0 will map to "No Jumps" while
#    value 2 is not in the dictionary so will display "Wide".
