Database sound streamer

How would you make a database sound streamer like spotify (ps. If i make one i Will share it to you guy's)

Look into DirectX, and I'd recommend getting familiar with DirectSound.

Thanks for the tip but are there antalet other Way?

You could use Fmod or DirectX for the streaming, and for the database you could use one of the several SQL packages. The one built into .NET is really easy to use, but it lacks a few of the more advanced features.
