Scratch

I added music to my game from my ipod, converted it to a .mp3 file, then I added it to my script, it seems to work fine until I hit my second script:
When I recieve: You Win!!!
stop all sounds(to stop music from previous scripts)
Switch to background: Brick-Wall-2
Play Sound: (my Music)
There is a red outline around this, I have tried using different music and changing around everything, even adding "stop all sounds" to a different script, I am confused, and if you could help, I would greatly appreciate it...
