Embedding a Soundcloud player in a post?

Yes it is. Copy and paste the Soundcloud embed code directly into your post. You can find this code via Share -> Embed on Soundcloud. Blot should turn that into an embeddable player. The embed code should look something like this:

<iframe width="100%" height="300" scrolling="no" frameborder="no" allow="autoplay" src="https://w.soundcloud.com/play...

Does that work? Please let me know if you have any questions about this or anything else.
