Can I code Spotify?

COPYDon't try to license a music catalog — build a self-hosted streaming server for music you already own instead: 1. A file scanner that walks a folder of your own audio files, reads ID3 tags (artist, album, track title) using an existing tag-parsing library, and indexes them into a database. 2. A library browser (by artist, album, or a flat track list) and a queue you can reorder, built on the browser's native HTML5 audio element for playback — no custom audio engine needed. 3. Playlists as a simple ordered list of track references, plus shuffle and repeat as client-side queue logic. 4. Stream from any device on your network directly, or via a VPN/tunnel for access outside your home network. That's a genuinely complete personal music server for your own files, a real weekend project. Out of scope: any licensed catalog beyond what you already own — that's a legal and business-development problem with no code solution, and collaborative-filtering recommendations at real scale, which needs far more listening data than one person's library provides.
