MusiCards Release Viewer
Read full descriptionHide full description
MusiCards is a visual MusicBrainz release browser and personal music player designed for exploring music data in a calm, clean and structured way. Search for artists, releases and tracks, scan CD barcodes, look up MusicBrainz release IDs, identify music using Shazam or Apple Music Now Playing, and explore detailed release, track and artist information. Connect an indexed local music library or your own Navidrome server to see which MusicBrainz releases you can play. Matching releases can be played directly in MusiCards with background playback and system media controls. The app organises music into five cards: โข SEARCH: Find artists, releases and tracks, scan barcodes, use Shazam, browse recent items and discover releases from Apple Music Now Playing. โข RELEASE: View cover art, release details, label information, release history and other available versions. Open the selected release in Apple Music when available, or play it from a connected library. โข TRACKS: Browse the complete track list. For classical music, composers, works and movements are displayed in a structured way instead of a flat list. Tap any track to see performers, creators and technical credits. โข ARTIST & DISCOGRAPHY: Read a short Wikipedia biography excerpt and browse a categorised MusicBrainz discography by year. English Wikipedia content is preferred, with another available language used when no English article exists. โข PLAYER: Play matching releases from an indexed local library or Navidrome. View artwork, track information, performer credits, playback source, audio route and decoded audio format. Control playback from MusiCards, the Lock Screen, Control Center or the system Now Playing interface. A MusiCards account is not required. Connecting a local library or a self-hosted Navidrome server is optional; the complete MusicBrainz browsing experience remains available without either. MusiCards is a personal project focused on clear and transparent presentation of music metadata. The app does not infer or generate missing information โ if data is unavailable from its sources, it is shown as missing. Powered by MusicBrainz, the open music encyclopedia. MusicBrainz data is available under the Creative Commons CC0 licence. Cover art is provided by the Cover Art Archive.
Sonarch

Sonarch plays the music you already own. Point it at folders on your Mac, a drive on your network, or a cloud account, and it builds one library out of all of them. Nothing is streamed from us, nothing is counted, and nothing about what you play leaves your device unless you ask it to. MIXES, ENDLESS AND YOUR OWN Your Mac or iPhone listens to 30 seconds of every track and works out what sounds alike, with no service involved. Play a ready mix named after its artists, or start one from any track, and it goes on for as long as you listen. Drift wanders as near or as far as you like, or winds down to your calmest music; Similar holds one mood. When an album ends, Autoplay carries on with music like it. A sound map lays out your artists by how they sound; start a mix from any of them. Narrow a mix to the artists or genres you choose, save it, and come back where you left off. With Sync, what one device analyzes, the others use too. ONE TRACK, HOWEVER MANY COPIES A track you have as FLAC and again as MP3, sitting in two different places, is one row in your library โ with every format and every place it lives behind it. EVERY FORMAT, GAPLESS BETWEEN THEM FLAC, ALAC, WAV, AIFF, MP3, AAC and Ogg Vorbis, with ReplayGain so a library built from many sources plays at one loudness. An album ripped as one file with a CUE sheet shows up as its own tracks. The output can follow each track's sample rate, and crossfade and silence trimming are there when you want them. SOUND THAT FITS YOUR HEADPHONES Import the AutoEQ profile for your headphones and everything you play is corrected, with its own profile for each output. Hi-fi style bass and treble controls are kept per output too, and a peak limiter lets both play louder without clipping. BROWSE VIEWS THAT FOLLOW THEIR RULES Any view can be restricted to the locations you choose, and a browse view takes rules as well, composed in its own filter engine. WHERE YOU LEFT OFF A browse, a playlist, every album and every saved mix each keep their own place, and quitting loses none of them. Bookmarks save any moment inside a track, to come back to later. WHAT YOU PLAYED, AND WHEN History keeps every play with the time it happened, counts a track that came around twice, and remembers the view each one was played from โ so it can be played again, or opened where it came from. Search all of it by track, album or artist. Bring in your Last.fm history, and Stats reaches back to years before Sonarch. FOLDERS, NETWORK SHARES AND CLOUDS Bandcamp, Dropbox, OneDrive, pCloud, S3 buckets, a WebDAV share or a Subsonic server, connected straight from your device with your own credentials. Your files never pass through our servers. Take what you want offline for the train. ACROSS YOUR DEVICES Sign in, and your likes, play history, tag corrections and playlists follow you between your devices. Pause on one and carry on from the same second on another. TAGS THAT STAY FIXED Correct a tag once and it survives every rescan โ written into the file where that is possible, kept by the library where it is not. ON THE MAC Send audio to another output with a keystroke, mid-track, without a trip into Settings. Schedule a start time and decide what happens when it ends. Drag in a ZIP from Bandcamp and it joins the library, with the shop's own tags stripped on the way past. ON IPHONE CarPlay, the Lock Screen and Control Center, through the system player. Control the Mac from your phone over the local network. ALSO An editable playing queue. Lyrics from your tags or from LRCLIB. Scrobbling to Last.fm and ListenBrainz. Stop after this track, album or artist, or pause after a set time. Genre categories worked out from your tags. Playlists, statistics, and sharing tracks as files. NO TELEMETRY, NO ACCOUNT NEEDED No analytics, no crash reporting, no advertising identifier and no third-party SDK of any kind. An account is optional โ the player works perfectly without one.

Verdict
