1999 - 2000 Oldskool Trance IDs. Please Help?? :)

I've been trying to identify these 6 enjoyable, oldskool Trance and hard trance tunes..

Some of these trance IDs could be b-sides which have long been forgotten which have featured on obscure record labels or possibly even white labels. Please take a listen as there are some fantastic unknowns in here which would be great if they were solved :)

Any help appreciated. Happy listening :) .

1. Note: very similar riff and synths to the Lange Remix of DJ Manta - Holding On but is not the same tune nor is it WGM - Dance Harmonia which comes up on Shazam.

I cant help you but nro 4 definately has distinctive swiss sound to it.
