API for controlling songs

[LCLPYT]

As a developer, I want to have an API to play a song to a set of players.

Possible methods (not the final signature):

void playSong(Song, Player);
void playSong(Song, Collection<Player>);
void stopSong(Song, Player);
void stopSong(Song, Collection<Player>);
boolean isPlaying(Song, Player);
Set<Song> getPlaying(Player);
