Songfeelic is an audiogender identity in which one's gender is positively affected by and/or changed when one listens to a specific song(s), often a favorite song. ('Positively' is defined by the user; it can be any change.)
Since one's gender is influenced by listening to their specific song, songfeelic is under the mutogender umbrella. It is also an audiogender and maybe considered a subset of cadenaesic. Additionally, songfeelic is similar to songvibic and electricsongfeelic.
