bvandeusenandClaude Opus 5.5	dabe1e052d	feat: genre mixes pick specific genres that don't share songs (#6933) ... The shelf had four mixes built largely from the same lo-fi beats: about 1,250 tracks carry Hip Hop, Lo-Fi, Instrumental, Downtempo and four more tags at once, and the near-duplicate guard compared artists, not songs, so each tag passed as its own channel. Genre selection now works on songs: - ListGenreMixCandidates returns each genre's track ids instead of its artist ids. - A broad genre, one whose songs mostly also carry clearly narrower candidates (Rock over Pop Punk and Ska Punk), is considered after the specific genres of its tier. - A genre is kept only when at least half its songs are not already in a kept genre. - Each mix leaves out songs tagged with a genre kept before it (ListGenreMixTracks exclude_genres), so a song is in one mix at most. The tiers, the minimum shelf and the minimum mix length are unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-07 14:55:19 -05:00
bvandeusenandClaude Opus 5.5	14debe2ea9	feat: genre mixes lean toward what the listener likes (#6921) ... Within a genre both halves of the mix were a uniform daily draw: a song played forty times was no likelier than one played once, and the unheard 40% ignored who the artist was. ListGenreMixTracks now draws each half by a date-seeded weighted lottery (Efraimidis-Spirakis: smallest -ln(u)/weight wins), so the mix still changes daily and holds within a day. - Familiar: 1 + ln(1 + plays) + 1 if liked, times the share of plays that weren't skips. - Unheard: 1 + ln(1 + the artist's plays + 2 x its liked tracks) + 2 x the artist's best similarity to the user's own artists, times the artist's non-skip share. An unknown artist weighs 1, so new artists still come up. Which genres are offered, the exclusions and the familiar/unheard blend are unchanged. DB tests check the lean averaged over ten days, and that a stranger's tracks stay in the pool. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-06 14:21:04 -05:00
bvandeusenandClaude Opus 5.5	dbaa8b7d57	feat: genre mixes — a daily playlist per genre you listen to, on a "Your genres" Home row (#6904) ... A new system playlist kind, genre_mix: up to 10 "{Genre} mix" playlists per user, rebuilt daily with the other system mixes. Which genres: library genres with at least 25 playable tracks across 3 artists, ranked in tiers — taste-profile genres first (matched case-insensitively, so ID3 "Post-Punk" and folksonomy "post-punk" are one), then genres the user has played or liked, then the rest of the library, which only tops a short shelf up to 4. A genre whose artist set is a near duplicate of one already picked (Jaccard >= 0.5) is skipped, so "Lo-Fi" and "Lo-Fi Hip Hop" don't both appear but "Alternative Rock" survives "Rock". A genre that can't fill 15 tracks gives way to the next. Each mix is 50 tracks: 3 in 5 the user already knows (played through or liked), the rest unheard in that genre, interleaved, with the usual per-album/per-artist caps. Tracks skipped twice and more often than played are left out. The order changes daily and holds within a day. Picks are stamped taste / taste_unheard, and genre_mix plays count toward rotation and the recommendation metrics. Migration 0102 adds genre_mix to the playlists variant constraints. Web and Android each get a "Your genres" row in name order, hidden until a mix exists. Kinds with several playlists per user now play by playlist id wherever the client used to test seed_artist_id (web card, detail page self-heal), keyed on the server's refreshable flag; on Android genre_mix joins songs_like_artist as not refreshable. The web detail page's "mix was rebuilt" reload now finds a Songs-like or genre mix by name instead of calling the by-kind shuffle, which those kinds don't have.
