Is it possible to play music streams on iOs devices
There are lots of possibilities. For example, you can stream directly to the device from the network.. Here is an article gauging three of these. It's a little dated, but you will get the idea. To stream directly from the macbook to your iOS device, you may be able to use Airplay. I think it depends on what specific computer and operating system you are using.

If these answers are dead ends, let me know and I can look some more. Please provide more system info, to help myself, and others make suggestions.
