Music restarts on next scene! (SOLVED)

I know it is a simple problem but can anybody explaine me how to make it continue on scene-switch.

It's pretty easy, actually.
Just don't play the sound again; it'll persist to the next scene!
To stop the soundtrack you need to actually stop the soundtrack (or play another one of type "Music").

Oh, and remember to use "Loop" rather than "Play" if you want to be looped over scenes.

Thanks it helped a lot!
