What format should I use?

When working on my game, I put music in a create actor event, but it makes a skippy sound in it
. It doesn't do it in real player, only GE. It kinda sounds like A High Quality song in a Game Boy like tone.
Also should I use mono or stereo. Which is better quality in GE?
I made just the menu of the game and you cant do anything except listen to the music. Escape = Exit.
