SongHub is an offline-capable Android karaoke and media-player app for phones, tablets, and Android/Google TV. Its documented user workflow is to use a personal song collection (optionally supplemented by downloaded samples), queue and play songs, and customize lyrics and visual backgrounds; a Smart Link phone can also control queuing, playback, and key/pitch. The README documents these capabilities but no source excerpts establish their internal wiring, so the graph shows only documented interactions. The supplied tree contains no feature-specific source paths; subsystem paths use the listed enclosing directory.
