Predator music in the movie.

I can't be the only person that noticed this. Within the movie and when the end credits began, the movie uses a variation of a track from the original Predator movie soundtrack by Alan Silvestri entitled "Billy and Predator." It's track 15 directly from Alan Silvestri's film music site:

The Infini credits say the music was performed by The Bratislava Studio Orchestra, Slovak Radio. Nothing wrong if they had permission to perform the song but Predator is one my favorite movies ever and many songs from the soundtrack, I think, are very identifiable to a lot of people. Makes me wonder why this movie didn't use an original track instead of something associated with a more known and popular movie.

Thoughts?
