Hi pone, I've tinkered with the script and have been using it for a while (4months) and it seems stable enough.. (I hope you don't mind?) Here's the script if you want. The SC tags has been fixed. It wasn't picking up them fully. And other modifications that I like. I shalll not be updating this on here as the base code is 90% Pones and I only fixed it for my own uses but seeing that it has been left idle for a while here it is:
MixesDB.com_3.3__Soundcloud.com_Direct_by__WWW_URL.src (18 KB)

I also was trying to get the [indexUrl] method working. I've used:
[BasedOn]=https://soundcloud.com
but it comes up with this:
Maybe you might be able to help me out and trouble shoot it seeing as you have more experience than me 
So far Ive tried:
[BasedOn]=www.soundcloud.com
[BasedOn]=http://soundcloud.com
[BasedOn]=https://soundcloud.com
but all come back with the same error.
