Lol yeah, i chose my own because of the part under the theme that said "Note: The themes here are more like an inspiration, and strictly speaking there are no specific "musical theme" for you to follow and that you can compose in any genre you want, so the submissions can be as diverse as possible." but then I saw that pretty much no one else chose their own theme (as far as I know) so I might have misunderstood it 😅 they might have just meant that you can compose in any style :P
Thank you! :)
