A PC has only one sound card, so only one sound stream out at the same time.
An amplifier or mp3-player or walkman or tablet or whatever also only processes one input simultaneously.
So to play 3 different musics at the same time you need 3 devices. But of course, if they get their music from a common data storage, you only need to have one music library.
