Would music I buy from the iTunes store go on non iPhones?

So I currently have an iPhone 4, I've had it for about three years now and it's not working nearly as well as it used to so I'm interested in buying a new phone. The Sony Xperia Z.

However I spent a lot of money on music from iTunes. Will I be able to listen to all that music on the Xperia Z?

You can transfer the music to your computer then to your Sony experia z! Hope this helps

Most likely yes. If you have all of your music on iTunes then all of that music is on your computer, just copy them to your Experia
