Hi there, always nice to see familiar people here!
Collab sounds awesome, I really like the overall sounds of your tracks, it could be a great combination with my melodies

Let's talk about that further in private.
That melody at 5:50 was inspired by 'Merry Christmas Mr. Lawrence' at bit, and I'm quit happy about it, it's stays in your head and sounds familiar.
Sometimes I wonder if there isn't a known song that sounds like it and I'm secretly inspired.
About that 17:30 track, funny you mention that. Actually it's a melody I created halfway the 90s in Fasttracker, way before Tiësto's rise

I used the original Fasttracker files for importing it in Fruity Loops, I have about 10 projects imported that way, and still some to do.
For other reference, check also my 2 artist mixes that are available on my SoundCloud page:

Except for 1 track I have all the original FLP/midi files still available, but I lost lots of VST's through time unfortunately
