Copy-paste this, and follow the instructions in the footnotes below:
(da:embed profile="website*" id="ID number**" width="300" height="80")***
*Just replace w/ the site you're embedding music from (YouTube, Soundcloud, etc etc.)
**Replace with the ID of the song you want to embed. For example, if you want to embed a track off Soundcloud, there's this string of numbers in the embed code (highlighted below):
so copy-paste that to where "ID number" is.
Or to embed it from YouTube, just copy-paste the string of letters and numbers that come after watch?v= in the URL.
***Also replace the parentheses w/ angle brackets (these things ) or it won't work (I had to replace them so people could copy the text)
There might be another way to do this, though, but this is how I do it.
