just wondering witch songs you guys think where the best for all 50 games 

There's a lot of great music but not gonna lie, I loved the MainGame music in The Fateslayer it works with the graphics to create a real eerie and unsettling feeling.  It actually gave me the chills at one point. My favorites in no particular order below. I'm including one from my game, which I did not make. Mine was made by Drexegar.

Klepsydra (Legends of Time Track 06 Level)

1000 Stars (Solar) & (End 2)

Chaos Between Realm (Track one)

Rick Starfield (Space Brigade)

Magnilo (Winter World)

The Drunk Time Traveler (Track 03 Japan)

I can't point out single tracks, but I love the music in Klepsydra and Rumblefest '89.

There is so much great music to choose from but the games with music that stood out to me are:

1000 Stars
Chronoknight
Chaos between realms
Paws N' Play
Paws of the West
Spacewalk 3030 (Really unique use of noise channel to create a cool atmosphere)

I have to say the music in my game is awesome! I did not have anything to do with making it tho! ha . It was David Ko and Raftronaut that made the tracks in my game and I feel they fit perfectly. I just want to give them credit and thanks for that! 

Ok . but NOT my game music..??? hmmm 

So far I dig the Space Walk soundtrack. fits that game perfectly.

Also Magnilo has some great music!! 

and Paws and Play had me jumping up and dancing!!
