# Music macros. As of 1.1.3, music is parsed as follows:

# 2. the [story]-level music key
# 3. any [event]-level [music] tags
#
# If you change the music at a lower level, the tags above it will NOT be re-parsed
# and your scenario will sound wrong. For example, if you set scenario music
# with the normal [scenario]-level music tag but change the music during the [story],
# it is never reset back to normal. Therefore, these macros are intended to catch
# instances like that. Of course, if you want something more elaborate, code it
# manually.
# A macro to define a standard playlist suitable for any level. The music is defined
# twice to catch instances where music is changed in a story and not set back.
