The Xara Media Player has always been a bit quirky:

1. Here is an example where if one drags the MP3 onto a popup, the MP3 will correctly play AND pause when the popup closes (unlike the standard audio tag) >> https://initiostar.co.uk/demo/xaraAudio/ - this seems to work for v19 and Pro +

2. In Pro + (current version) you can drag and drop multiple MP3s to create a fairly simple Jukebox style plugin >> https://initiostar.co.uk/demo/xaraMedia-Player/ - the issue thereafter is that as one switches between tracks, each track pauses at its current position; you can overcome this with a reload command and probably other ways too.

3. Here is an example of Acorn's 2024 code variation that removes the need for a short blank MP3 (known as load.mp3 in earlier examples) >> https://initiostar.co.uk/demo/Audio-Player-24/

4. Here is a more creative plugin that adds additional descriptive content for each MP3 >> https://initiostar.co.uk/demo/AudioPageHolder/ - it shows the plug-in embedded into the main site and works for desktop and mobile.

All the above were first created as "plugins" with a 640px width and Scale-to-fit-Width. In the examples here, they would be published to a main website with a file name such as "audio-player"(not index) and called into the main website using a placeholder.

For [1] I cannot tell if it works for the perpetual licence v20, but all seems OK with Pro +

The Xara Media Player does generate errors that can be seen when you Inspect any site using it in a browser [ right click to tab Inspect ] but other than that it seems to work OK.
