The video backgrounds (aka movie sheets) only appear in 1/5 views, for that matter all themes are fine.
With music everyone has it’s likes and dislikes i don’t really think a recommendation is going to help you here.
Simply download a few themes, they are free after all…
unpack the the theme pack and copy the theme folder in .wd_tv/themes on your Live Hub
you can select the theme from setup/appeareances/
it’s very easy
