It's remarkable to me how few decent html5 audio extensions there are available. I've tried a few audio players, but with Flash appearing to be in its twilight years (as far as mobiles etc are concerned) none of them really did the job I wanted on all devices.
Enter the SJ HTML5 Audio Player. See, not only is this a great player, beautifully styled as default (and style-able), it's also simple to implement and use. However, if you're an awkward beggar like me, the superjoom team will help. Did I say 'help'? Waaaay above and beyond the call of duty. The team worked for the better part of a day trying to accommodate a request I made, respectfully and with no complaint throughout.
From what I gather, whatever limitations the player might have right now will be addressed in future upgrades, so they're clearly not a static bunch of developers either. The instructions are fairly non-existent, but then again, you don't need much instruction to use it from scratch.
I'm very wary of putting even a small amount of money down for paid extensions. The SJ HTML5 Audio Player was worth many times more than I paid for it and I only wish I could give it and them 10 stars.
Superb after-sales service for a product that's pretty near perfect to begin with.
