Sorry after releasing SONGKONG 3.22 earlier today I found a serious bug with my fix for https://jthink.atlassian.net/browse/SONGKONG-825 . My solution is incorrectly matching a regular expression rather than a literal with the effect that if you enable ‘Rename Songs based on Metadata when Matched’ the first character after every folder seperator ‘/’ is being replaced by an underscore.
Its too late here for me to safetly do a new release tonight so instead the latest download on the Jthinkwebsite is now back to SongKong 3.21 I would advise you to download and install this until I have fixed the problem I expect to do this tomorrow and release as SongKong 3.23,. Alternatively if you not enable ‘Rename Songs based on Metadata when Matched’ the problem will not occur.
