Hi Rgiuly, How are you. I remember this project, as it has been re-posted now. We will have midi file converted to mp3, as and when it is added, and for existing or added through the different methods would be converted to MP3 as a scheduled job, which we can handle as cron job. then, I need to check your existing design of the website. If I remember correctly, you had provided wire frame of the webpage in the last post. Please share the same again. Then, each MP3 Song would be either would have encrypted media / public media location, which can linked with the browser media player to play it. I did such thing for one other project in past, which was for weekly update of region wise songs available to play on the page, which can be played on click.
Looking forward to work together.
