Morning Rick,
Looks like Soundcloud have got wise to hotlinking files without using their player (which makes sense – it’s using their bandwidth). I did a right click and inspect and then right click on the file name to open in a new window and it comes up with “forbidden”
Probably best way round this is for me to add a form field to allow using the soundcloud embed code, so you can have a soundccloud player (or any other providers share code)
https://help.soundcloud.com/hc/en-us/articles/115003566828 is their link on how to get the code.
