Meld: Android Music Client Unifying Spotify and YouTube Music

Overview of Meld

Meld is an open-source music client designed for Android devices that combines the personalization features of Spotify with the streaming catalog of YouTube Music. The application allows users to leverage their Spotify accounts for recommendations, search queries, and home screen content while streaming the actual audio through YouTube Music infrastructure.

Core Features and Functionality

• Dual-Platform Integration: Uses a user's Spotify account for metadata, playlists, liked songs, and discovery, while utilizing YouTube Music for playback.
• No Premium Required: Operates using Spotify's data APIs rather than streaming directly from Spotify, meaning a free Spotify account is sufficient.
• Built-In Authentication: Connects to Spotify via an in-app WebView login without requiring external developer setups, Client IDs, or manual token management.
• Optional Lossless Audio (Qobuz): Includes an experimental, opt-in feature to route audio through Qobuz FLAC catalogs using ISRC-based or fuzzy track matching, with a silent fallback to YouTube Music.

Installation and Verification

Official releases of Meld are distributed exclusively through its GitHub repository as `Meld.apk` files. Users must enable installation from unknown sources on their Android devices. To ensure security, users are advised to avoid third-party mirrors and check official project links.

Platform Policy Considerations

As an unofficial third-party client, Meld interacts with platform APIs under specific operational conditions:

• Spotify: Utilizes data APIs in a read-only manner. Because it does not stream audio from Spotify or artificially generate plays, the risk of account action is considered low, though users operate such clients at their own discretion.
• YouTube: Streams audio using underlying YouTube infrastructure. Logging into a Google/YouTube account within the application is optional (primarily for age-restricted or region-locked tracks) but carries a non-zero risk associated with third-party client policies.
