Its in MusicVisualisation.xml

OSD are just the buttons

 Thanks for feedback.
But I`m a absolute newbie. Do you have some more specific info about.

BTW is it possible to change the text color of the artist bio?
I search the forum and I`ve made some changes on my XML files, but I couldn`t figure out. 

Basically all the layout for that screen is in MusicVisualization.xml.  There isn't any real documentation for what's included there, so if you want to make changes you're just going to have to read through all the XML, find a section you think is where you want to be, and make changes.  You can also check out the skinning manual to get a sense of what's possible:
