Example of using HTML5 as a music playlist. This html would be put in a directory and all the mp3 files that it references in a subdirectory called mp3. The whole thing can be written to CD-R where this html serves as the music playing application (and MP3 CD-Rs will autoplay in most non-interactive devices).
