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?

Meanwhile I did a short research and it seems the most effective devices for what I need (at a reduced price) are the Chromecast Audio, the Dayton Audio Wave Link and similar products.

Thank you for the suggestions. I see some interesting solutions...
What I have right now is a bunch of old style amplifiers. Some solid state, some tubes. No streamers, no modern receivers/amplifiers with network connectivity.
So I'd like to try something like a dongle that I can connect to each of the amplifiers to receive the signal (coming from a computer or a phone). I think there are already some receiver devices that can be synchronized in order to receive the same signal at the same time. Am I right?
