I’ve recently developed a WordPress plugin called PressPlay Lite, which is now hosted on wordpress.org. PressPlay Lite offers music lovers the easiest way to play MP3s on their WordPress site. Simply insert a link to an MP3, and PressPlay Lite will automatically prepend a play/pause button. PressPlay Lite is powered by an extremely slimmed-down version SoundManager 2 (http://shillmania.com/projects/soundmanager2). The simplicity of PressPlay Lite empowers end-users to manage their own audio and rest assured that their guests can listen from any browser on any device.
I have used it on several sites, including my personal music site.
If you’re looking for thee simplest, cleanest, most-flexible way to play music on a WordPress site, please give this plugin a shot. And if you end up liking it – why not make it official? Please submit a rating & review on wordpress.org. Thanks!
