Rip a CD once, drop the files into a folder, and QM Music turns that folder into your household streaming service: phones, desktops and web players all browse the same library of MP3, FLAC, AAC and WAV files, organised by album, artist and genre from their ID3 tags and cover art. Because the server speaks the Subsonic API, Feishin, StreamMusic, Amperfy, Substreamer and Music Assistant sign in with an address and a login, no app-store rental required. Point a phone on hotel Wi-Fi at your home collection and it plays. At home, playback can pull pristine FLAC; on mobile data the transcoder serves an MP3 or AAC stream sized for the train ride. Keep a family happy in the background: each person gets an account with individual permissions, favourites that sync between devices in real time, private playlists and lyrics following the current track. Finding something new to hear takes recommendations from listening history, similar artists and similar songs, and two years of play history sit behind the statistics. Scheduled scans collect fresh rips automatically, refresh happens on demand when a disc lands, and the catalogue idles around 150 MB of memory on the server.
