When a song has no image associated in the DB, the default image is not shown. In dev this happens whenever an image request returns a 500 (which is not great and should be fixed independently of this), in prod it instead returns a 415 and doesn't show the image.
Default image now works after #36, however now the frontend sends its requests for the images to the wrong URL, thus receiving no answer and displaying the default image for every song.
