Overview

Crates is a music app that brings local files and online collections into one searchable library. It is built for listeners who want to organize, play, and discover music without splitting their collection across separate services.

The app supports desktop use on macOS and Windows, with mobile apps and browser extensions mentioned on the site. It combines file playback, in-app streaming, metadata enrichment, playlist management, and community discovery in a single workflow.

Features

Unify local and online collections

Import local files and collections from hard drives, network storage, USB drives, Discogs, and connected playlists or libraries from YouTube, Spotify, and Apple Music.

Listen from files and connected services

Play MP3, FLAC, WAV, ALAC, AIFF, AAC, and similar files, then stream in-app from YouTube, Bandcamp, SoundCloud, and Apple Music.

Enrich and organize metadata

Automatically fetch artwork, release details, genres, label information, and other metadata, then calculate BPM, key, and waveforms for organized browsing.

Manage a searchable library

Tag, rate, search, and create playlists, with metadata that can be written back into files so the library stays usable outside Crates.

Capture music as you find it online

Use the browser extension or drag-and-drop supported links to save tracks while browsing, and keep them in a universal play queue.

Sync to mobile devices

Sync the same library structure to mobile, download converted files to save space, and preserve playlists and metadata on the phone.
