Unknown Songs: Etsuko Nishio Tape (Full Audio) [7/11 SOLVED]

Описание: The full audio from a gravure tape of Etsuko Nishio, featuring several unknown songs.
We only had the audio of songs 6 and 7 previously available, and a few seconds of #8, but now we have them all for the first time.
Something interesting it that in the credits, it lists the name Taichi Iwasaki under music, but I can't find anything about him, or anyone in the credits.
Links: Youngshield's uploads of songs 6, 7, and 8:    • Unknown 80-90's Japanese songs - Etsuko Ni...  
Hairegu's upload with a bit of the tape (NSFW):    • Etsuko Nishio takes a bath in a bowl 西尾悦子  

I also have the full tape if you're interested in that, but I can't really link it here.
