UX Drag and Drop Website

The site is for children 8-18yrs. As you can see from the image below, on one side the user will type her/his story and then drag and drop an audio file that fits it. The user begins by selecting an emotion or quality of the music she/he wants, listens to the selections, and then drags it next to the corresponding section of the story. When complete, the story can be printed and the music can be streamed or downloaded. The text field will have Grammarly embedded and be properly formatted for printing. The music will be downloaded as a single mp3.
