Yes, but is does take a little setting up. First, you need a Bluetooth device that connects to your iTunes library – your mobile phone or laptop should be able to do this.
Turn the Bluetooth on in that device and make sure it is in pairing mode.
Alexa will detect your device and instruct you to select Echo from the Bluetooth pairing screen. Once your device is paired, you’re ready to go. Just open the app you normally use for iTunes start enjoying the tunes!
