WordPress recently made improvements in the audio and video area to include media players for each. This improvement means you can easily serve up audios and videos hosted on your own server through your WordPress site. In addition to single audio and video files, you can also choose to serve up a playlist of either.
Galaticos support this feature natively, meaning you can create and edit audio/video playlists in WordPress and they will display nicely in the frontend. If you don’t know how to add/edit audio, video playlists, this is a good tutorial from WPMU DEV blog.
