This module should be further up the chain as I believe it is a great solution and quite elegant.
Tested on FF, IE, Chrome, Safari, iPhone, iPad and works with ALL platforms well. Easy to install and setup. Hides away at the top/bottom of a page and then you can set an MP3 link anywhere on a page to have it pop up the player and start playing. Being a module it also allows you to have a pre-set playlist ready to go and this can be different for each page.
I had initial issues getting the player to show on my site but their support was quick to log into my site and fix the issue. They also responded to an issue I was having passing images to the player from page links and researched the issue and provided me with a fix. For the $$$ and functionality + the support I don't think you could go wrong if you need a good HTML5 player.
