^^^^I just can't figure it out. I'm feeling a bit stupid at the moment, and that's me working with another tab showing me what to do!
Aww, I can never remember how to do it either!
I just go to advanced reply, write my song - artist, right click and highlight it then go to the wee link thing at the top and type the youtube address in there.
Hope that makes sense, I know now't about computer terminology.
