Jazz Jackrabbit music similarities

[TomoAlien]

So, my older noticed that the Jazz Jackrabbit theme sounds like "Unbelievable". This song was originally made by EMF, but it was covered by some other bands so this'll be the version I'll be talking about.

Here's the part:
EMF - Unbelievable: 0:41 in http://www.youtube.com/watch?v=waacof2saZw
JJ1 Theme:http://www.youtube.com/watch?v=mnnFFEStA3c
JJ2 Theme:http://www.youtube.com/watch?v=_E8LSvpyULw

Tell me what you think and if you find any other similarities.

There are more simularities, sometimes artists used an older track to be implented to games.

Streetwise (TSF) for an example, this was an original from basehead with dope in your mind.
