Artemgender is under the Audiogender and Musicgender umbrella. Artemgender is when your gender changes to the gender of the artist you are listening to. This usually only happens with certain songs or artists, and is rare to react to any music.
Artemgender is not so much of a gender itself, but more of a term. Those identifying with this term will usually have a base gender that they usually identify as, but when listening to music, will change gender. Here is an example:
Alex identifies as a male most of the time. He's at his friend's house when his favorite song by taylor swift comes on.
Alex: Hey Sam, while this song is playing, can you refer to me as a girl?
Sam: What do you mean? Aren't you a boy?
Alex: Im Artemgender, if you look it up, you'll understand.
Pronouns: Pronouns usually depend on current gender. If you are listening to a male artist, you might use he/him pronouns, but it's all choice of the individual.
