Are those part of the SmartSound Sonic Fire Library?
If so, you will want to go to the SmartSound Web site: http://www.smartsound.com/ as they have all of the licensing info for their music. You should be fine, but I would check, just to be sure.
Thanks for the comment. I found this track in the menu at the bottom (Button = music). But I just checked it again... there is a menu "smart sound" and I remember I was once on that link and it opend sonicfi. So are these sounds in a free licence?
I don't think any user here will be able to tell you if an individual file is free, or not
You need to go to the owner of the file to find out... such as the link Hunt provided
