how often do you write songs (if you keep track of those sorts of things)?
before beginning production on a new song-video, i typically do a large writing session where i generate many new song ideas and develop many of my existing song ideas, then i do a selection process to pick which one will be produced next, then i finish the writing for that one only. so if we're talking about the complete writing of a song, that mostly happens as often as a song-video is produced/released, immediately preceding the production
