overriding textile when necessary?

Hi,

I am using some custom defined tags, that I call and <track>.

For instance, I’ll have something in the post that looks like <track>Artist – Title</track>Song description and it will then call an mp3 with the filename Artist – Title.mp3.

The problem is that Textile is turning my hyphen into an en dash, and in this case I need it to stay a hyphen because it’s in the filename.

Is there any way to override textile in certain cases? is there a better way to do what i’m trying to do? Thanks in advance.
