The sidebar had a Home item that fell through to "Coming soon". What was missing was not another view of the library — four of those exist, sorted and complete — but the opposite: a complete, sorted library is exactly what gives you nothing to play, because every entry point into it is alphabetical and identical every time you open the app. So a shelf is a *reason*, not a filter. Each one answers a different question you might be asking when you do not know what you want (what was I listening to, what is new, what do I keep coming back to, what have I forgotten, what fits, what would I never pick myself) and each says which question it answered — a row of covers with no explanation is just another grid. Two consequences run through it. Shelves are built from what the user actually did — play counts, last played, import order — with random sampling only where there is no signal to use, so randomness is the fallback rather than the design. And a shelf with nothing behind it is omitted instead of rendered empty: a fresh library legitimately gets three, and an empty row labelled "on repeat" would be a lie. The queries return album ids and nothing else, joined back to GetAllAlbumsWithDetails in Go, so the album projection keeps having one definition rather than one per shelf.
