I don't know about 8-tracks, but I have/had plenty of 33s and 45s.
33s:
New Edition: All of them
Cameo: Candy
EU: Da Butt
I can't remember what else I had
45s:
Teena Marie
Stevie Wonder
Barry White
Deneice Williams
Michael Jackson: Off the Wall & Thriller
and a host of others
The Thriller album was for me (and of course all the 33s were mine
) . The rest were for my mom. I just hung on to them after our record player was played out. I didn't have the nerve or will to throw them out. I kind of want to buy a record player so that I can listen to them. That old vinyl sound is cool.
