Different systems playing same music simultaneously


I have four different systems located in different rooms.
Is there a way to make them play the same music like a multi-room system?
Could I send the signal from one source to all the systems at the same time?
Each system has its own amplifier and speakers.
Is bluetooth an option? Can I use a transmitter and several receivers?
Does anyone have this kind of setup?

No, not at all too advanced. Knowing that cell phones in the room destroys the sound is, um, like day 1... helllllooooo
