Tracks from about 1991-92 in Youtube-Videos

Hello,

I'm searching for 4 tracks in 2 Youtube-Videos.
First video is this one:

Lost in Music Teil 1/5 - YouTube
(Lost in music - Techno/Trance, 1992)

There I'm serching for the track from 7:06 min to 7:29 (two tracks after Marusha - Rave Channel).

The second video is this:

Technoparty 1.6.1991 Come In vor 20 Jahren ! - YouTube
(Technoparty 01.06.1991)

There I'm interested in 3 tracks. At first this, which starts at 4:44 min (the track before Space Trax - Atomic Playboy), at second the track from 7:47 min to 8:01 min and at third the track which starts at 9:36 min (the track after Outlander - Vamp).

Thank you for any help.
