Were you aware you can run SongKong from the command line
i.e songkong.sh -w /Music
this will use whatever the settings were from the last run
(To change the settings you would have to run in GUI mode or possibly manually edit songkong.properties but I wouldn't recommend it)
However a serious regression was introduced in 1.4 meaning you could only run from the commandline in trial mode, however this is fixed for the forthcoming SongKong 1.5 release that should be available next week.
