cat flaccy/FEATURES.md
Albums, artists, songs, and playlists with search, sorting, and stunning artwork. Scene releases and messy folder names are identified and cleaned up automatically on import, and the first scan reports every stage with live counts instead of leaving you at a spinner.
Albums play the way they were mastered — no gaps, no hiccups between tracks. Your queue persists across launches, so the music picks up exactly where you left it.
Synced lyrics with tap-to-seek and a full-window Now Playing screen — on Mac, album art, lyrics, and your queue sit side by side over an ambient, palette-tinted backdrop. AirPlay, a sleep timer, Lock Screen and Dynamic Island controls, and full light and dark mode throughout.
Sign in with Last.fm and every play is scrobbled — even offline, with automatic retry. Loved tracks, listening charts, and artist bios matched to your library.
Your listening year as shareable story cards and a poster — top artists, albums, and the numbers behind them, rendered beautifully from your own plays.
The built-in Listening Guide explains what actually reaches your ears — Bluetooth codecs, why lossless can't reach AirPods, and when FLAC is worth it. No snake oil.
Sync albums to your watch and play them offline — gapless, shuffle, repeat — no iPhone in your pocket.
Codec, bit depth, and sample rate on every track — honesty down to the file.
A native Liquid Glass Mac app, built for the desk, that wears the color of your music — the whole window takes on an ambient palette pulled from the album you're playing. Watch a folder and new files appear instantly, control playback from the menu bar mini player and your media keys, sort a multi-column song list, browse keyboard-first, and export full-resolution Year in Music posters. On the Mac App Store now.
A native GTK4 app for the penguin at your desk, and one of the best-looking music players on Linux: an adaptive shell reflows from a phone-width drawer to a full desktop layout, and an adaptive theme engine tints the whole app with the dominant color of whatever's playing — ambient gradient backdrops, glass cards, a glowing now-playing pulse, and a full-window Now Playing that slides synced lyrics and your queue in beside the cover. Gapless GStreamer playback, media keys via MPRIS, Last.fm scrobbling, tap-to-seek synced lyrics, and listening stats, in light or dark. Free and open (1.8.0). Install with one command — curl -fsSL https://raw.githubusercontent.com/guitaripod/flaccy/master/linux/get-flaccy.sh | sh — or from the AUR with yay -S flaccy-bin.
man flaccy
Copy music over USB or pick files in the Files app. Flaccy shows you exactly what it is doing while it indexes — files found, tags read, albums built — and identifies and cleans up messy folder names and scene releases automatically. After that it opens straight into your library.
Browse albums, artists, songs, and playlists, then play gaplessly with synced lyrics, ambient artwork, AirPlay, and full playback controls on the Lock Screen and in the Dynamic Island.
Sign in with Last.fm once and every play is scrobbled — even offline. Watch your charts grow and unwrap your Year in Music.
