+## Description

+
+## Description
+
+`lib/music_library_web/live/stats_live/top_albums.ex` (201 LOC) and `top_artists.ex` (168 LOC) share near-identical structure: same `mount/1`, `update/2`, `handle_event/3` callbacks; same time-period tab UI; same `assign_async` pattern with `reset: true`. Only the data source and item rendering differ.
+
+Additionally, `top_artists_by_period/1` is `def` (public) while `top_albums_by_period/1` is `defp` (private) — a visibility inconsistency.
+
+## Expected behavior
+
+Consider extracting a parameterized `TopByPeriod` component that accepts data-fetching and rendering callbacks. Fix the `def`/`defp` inconsistency.
