// get the track info using get state
await CodyMusic.getRunningTrack().then((track: Track) => {
    // - "genre" will be empty from Spotify
    // - duration is in milliseconds
    // {artist, album, genre, disc_number, duration, played_count, track_number, id, loved, name, state, volume}
});

// play a specific spotify track
await CodyMusic.playTrack(
    "spotify",
    "spotify:track:2YarjDYjBJuH63dUIh9OWv"
).then(result => {
    // track is playing

});
await CodyMusic.getRunningTrack().then(result => {
    // result will be the best effort track that is playing.
    // i.e. if you have your itunes app running, it would show you that track
