No, it isn't.
Whats the going price for a proffesional musician?
How long is a piece of string? ( From end to end, I remember :P )
You could pay anything from $100 to $1000 for a piece of music, depending on the artist, where they live, what their day job is, how much experience they have, etc.
If you're just making a free game, there are plenty of sites with free music on them, that you're allowed to use. Achim Tober's site is one that springs to mind. Shouldn't be hard to find.
If you want something a step up without spending too much, there are dozens of sites selling royalty-free music from $25 and up per track. It's non-exclusive so other people may use the same music in other projects but there are so many thousands of tracks out there, that it's unlikely to be a problem.
EDIT: And looking up, I've just realized this was someone else's thread. Sorry for going off topic.
