Help with music editing sowtware.

So I can use software but need a free or under 10 dollar (lol) software program. My brother has Abobe Soundbooth but is tired of me using his computer so you know of any software?

I believe Audacity is free and…well… Good for a free program I guess. But you can get Music Creator 5 which IMO is > Garageband for about $25. I’d go with that.
