Music and sound effects tool for Flash game

Hi everybody.
Dunno if I’m posting this thread in the right place, I hope yes…Looked around and didn’t find another thread with the same question.

Can anybody suggest a tool (possibly free, Open Source or whatever) to create music loops and sound effects to use in the game I’m gettin’ mad on? I’m spittin’ blood programming the little ungraitful artificial intelligent piece of @#**, but I think that a good music score is essential…Along with nice sound effects.
What tool do you use? Anything not too difficult (I’m not a composer, you know).

Thanks in advance!
