Cross-platform Music Fallback Engine

Search songs across platforms in one UI and auto-fallback to a playable source, with no single-platform lock-in

Problem

Listeners often hit membership or licensing restrictions that block a song on their usual platform, forcing them to switch between NetEase, QQ Music, Kugou and others to manually find an alternative. They also want playlists and history stored locally without creating an account.

Solution

A desktop aggregated player: one search shows sources and quality labels across platforms; when a track is restricted, it automatically matches a playable version on another platform by title, artist and duration without interrupting playback; playlists and recent plays stay local.

Users

Heavy listeners who use multiple music platforms and are sensitive to licensing restrictions and switching friction

MVP

Search and playback across 2-3 platforms; version matching and fallback by title/artist/duration; local playlists, favorites and recent plays; line-synced lyrics with translation merge; clean ad-free player UI

Revenue

One-time purchase or low-cost annual subscription for multi-platform fallback and lyric enhancements; free tier limits fallback count

Why now

Music licensing is fragmented across platforms, cross-platform listening is a persistent pain, and a local-first no-signup product fits privacy expectations—indie developers can validate quickly with a desktop app
