(1) There is a now a Custom mood category. You can add your own mood words, if not covered already, in this category. So maybe you like "Angelic" which is not there. You can simply add it under "Custom" and it will always be there for you.
(2) Songs (Title + Moods) are now stored in the cloud, not as "mood" files on your local hard drive. Every user has their own space up there for their songs as well as the custom words as in (1).
There is a demo video on the site if you want to learn what the program does before considering a purchase ($5.99 subscription for life). The video does not yet cover the custom mood category. You can also access the video directly at: https://syncmoodtag.com/_video/sync-mood-tag.mp4
Also, I'm working on a major release for later this year which will offer genres/sub-genres and keywords (potential scene uses, etc.). Anyone who buys in now will be grandfathered at no cost into the new version which will sell at a more appropriate higher price ($ TBD).
Hey Casey -- FYI, I made use of your Synch Mood Tag app today for the first time. It was VERY HELPFUL! My brain was getting stuck thinking of appropriate moods/tags and this broke the logjam! Thanks so much.
