If the song finished, will it go all over again or it "dies"? Also, is it needed to stop the audio stream when the song has finished, let's say with a timer?

When the song finishes, it finishes. If you want to replay it make a command that actually plays it and wait till it finishes and re-type the command. Or, with a timer I think it can be done but you need to know how many minutes the song is, (Length of the song).
