Song Ranker

Rank every song by any artist head to head (Elo), then compare your list with friends and with the crowd. Live at https://ellioshow1.github.io/song-ranker/

The successor to the Artist Ranker (Deezer edition), which stays untouched at https://ellioshow1.github.io/artist-ranker-deezer/. Rankings made there can be brought over from the home screen: picks are copied (never moved) and replayed as Elo ratings.

Features

• Song catalog from Deezer (no login): the artist's albums, singles, EPs and compilations, plus features found through their top tracks and a name search.
• Duplicates handled properly. Tracks with the same ISRC are one song. Titles are compared without feat. credits and noise like "Remastered 2011", "Radio Edit", "Single Version" or "Bonus Track". Live, remix, acoustic, instrumental, sped up, demo, re-recorded ("Taylor's Version"), extended, skit and other alternate versions stay separate, each type toggleable. Pick which version represents a song, split a wrong merge, or merge a missed one; same-title leftovers are listed under "possible duplicates".
• Filters and presets: release types (albums, singles & EPs, features, greatest hits & compilations, live albums), version types, minimum length, years, specific albums, the crowd's top N, manual adds/removes, add by Deezer link.
• Elo matchups with 30-second previews, ties, skip, undo and keyboard shortcuts. Rough ≈ 4 matchups per song, Solid ≈ 8, Sharp ≈ 14. Every song always has an exact place.
• Album ranking from the average rating of each album's songs.
• The crowd: Deezer popularity (driven by recent streams) as the robot. Compare shows agreement, your hidden gems, what you think is overplayed, a scatter of every song and both top 25s.
• Sharing: a link with your whole ranking and your hot takes (notes on songs), an image of your top 10/25/50, or text. Opening a friend's link shows their list against yours and the crowd; save it to compare any time.
• Stats tab: albums at a glance (each album's songs as dots by place, albums ordered by average place) and how your ranking took shape (every song's place after each round of matchups, with the biggest climb, the biggest fall and who has held #1). Follow up to 8 songs through it. Upsets and rivalries: picks your ranking now disagrees with, songs that met more than once or tied, and neighbours at the top that never met, each with a rematch button.
• The matchups behind every song: its song card lists every matchup it played (opponent, result, rating change) with a chart of its rating game by game, its best win and worst loss. On desktop, hovering a song in the ranking shows a summary.
• Group ranking: blend you and any saved friends into a consensus list, see the most divisive songs and who agrees with whom.
• Optional Spotify playlist export (matched by ISRC), and backup/restore.

Everything is stored in your browser (state in localStorage under songRanker.*, catalogs in IndexedDB).
