This is my personal opinion and I realize that other may not like it, I only ask to consider it as an alternative.

Personally I prefer the Sidebar layout with 3/5 bottom bar over the current layout in Youamp. It looks more polished and is more easier to navigate. Examples of this layout would be:-
(Home, Search, Albums, Artists, Library) in Bottom Bar
(Home, Search, Albums, Artists, Library, Genre, Folders, Liked, Stats, Queue ) in Sidebar
Settings, Sort, Edit Metadata etc as options in hamburger menu in top right
