Comment 12 for bug 851424

requesting ayata-design inpu on the issue, that will need design work

you have some good points, some small comments:
- you seem to assume an user collection is a fixed set, it's not, most users buy music and copy things around, the genre and decade represented in their collection change
- categorisation helps, even if it's not a perfect match of how you would sort your music, go on amazon or any website selling music, they will have section for different genres
- empty categories (or decades) should be listed, the same way your email client doesn't stop listing your inbox when it's empty, or that menu prefer to make items unactive rather than hide them, bookmarks in nautilus don't go away when the directory they point to is empty, etc ... the reason i.e menu items are not hidden is because it would make the interface harder to learn and use, hidding a decade on the timescale would also be weird
