I'm still getting a hold of the SoundCloud API.

The main issue is the way to embed the song. Unlike youtube, you need to get the track ID. One way is to use Javascript. However after parsing the link (check if the wire post is a link or not) Javascript is not working like it should. On a regular PHP/HTML page, the Javascript way works. Since it doesn't work I had to study the SoundCloud API.
