Modify an HTML5 audio player

Hello, sorry about my english I need to make the following changes to the attached player: 1. I want to add to the "loading" image to be displayed while the mp3 is still loading. Example: [login to view URL] 2. When the audio finishes playing, the button, which used to be the "[login to view URL]", should return to "[login to view URL]" OBSERVATIONS 1. The image "[login to view URL]" should be displayed every time the mp3 file is loading 2. The player should work in all browsers (mobile and desktop) 3. If the user wants to "interrupt" the loading of the audio ([login to view URL]), it simply clicks on the button so that the load stops, and then again the image "[login to view URL]" Please download the attached file
