ML-65	Move scrobble queries out of Records context	Done		2026-04-20 08:55			https://github.com/cloud8421/music_library/issues/110	medium

Description

GitHub: created 2026-03-12 · updated 2026-03-12 · closed 2026-03-12

Problem

MusicLibrary.Records directly queries LastFm.Track in three places: get_last_listened_track/1, play_count/1, scrobbles_for_record_query/1. This is a cross-domain leak — scrobble data belongs to the listening/stats domain.

Proposed solution

Move get_last_listened_track/1 and play_count/1 into MusicLibrary.ListeningStats. Update LiveView callers (CollectionLive.Show, WishlistLive.Show) to call ListeningStats instead of Records. Remove LastFm.Track alias from Records.
