This Joomla plugin will create a table of every MP3 in a specified folder. It displays the ID3 information of each track with a link to download or play the file in the browser
That seems like a totally reasonable use case, but I don't see this likely to be added any time soon by me, as I'm only very poorly tending to the most basics of maintenance. You're welcome to fork or offer PRs.
Great plugin but would be nice if I could use this on all of my S3 buckets instead of the folder having to be local.
