Point cmus at a small music collection with mixed codecs and messy tags. Test library search, playlists, queueing, keyboard controls, and audio output on the device where you will listen. Restart it and confirm playback state behaves as expected.
A lightweight terminal player is a good fit when your collection is local and shortcuts help. Keep music files and playlists portable, and verify that less technical users do not depend on an interface they find opaque.
