What it is
RTLMusic is an Android music player built with Kotlin and Jetpack Compose, forked from ArchiveTune and taken in its own direction. It's presented here as a flagship RTL project — not because it's necessarily RTL's most popular, but because it's the music project closest to the creator's heart.
Development story
Work on RTLMusic has focused on stabilizing a large codebase merge: resolving Compose library version mismatches, fixing reorderable-queue bugs, repairing lyrics-fetching, and clearing up UI compilation failures left behind by the merge. Playback for online tracks is handled through a YouTube-sourced streaming approach — NewPipe Extractor, InnerTube (YouTubei), and the Piped API.
Privacy approach
As a locally-run Android player, your library and listening data stay on your device. Streamed tracks are fetched on demand through the extractors above; RTLMusic doesn't build a separate profile of what you listen to.

A public changelog and release notes are planned — see the roadmap for current status. No release date is announced yet.
