hi,
I couldn't find those files anywhere either. Still, I strongly believe "Testing Faster" was composed by Echo/LSD. It's not in our archive, but it's very much like his work. Maybe we could ask him

. Crown ?
Now "We are different" is very difficult one to trace, also, but being a converted file suggest indeed it comes from an Amiga demo, and probably a recent one (i.e. > 1993). It might also be a music entry at a party.
Ah well, I'm afraid that's the best I can do for now.
