Albums you own on formats that aren't Vinyl, CD or Online

I have several vintage cassettes from the 80s and 90s that my parents gave me but our cassette player broke so I can't play them

Atsuover's "Smoke 'Em Out Struggle" on Cassette, I would plan to get N.W.A.'s "Straight Outta Compton" on the format as well if official copies weren't so expensive or damaged in some way.

Though I recently ordered some blank tapes, cases, and J-card paper so I can convert a few albums to cassette. 

I just got Sgt. Peppers Lonely Hearts Club Band on Cassette which came in a Trader Joes cracker box (No Joke)

I have so many tapes....

I used to actively collect cassette tapes, and have amassed a collection of somewhere around 400 of them, excluding any recorded/blank ones.  Artists range from Tom Petty & The Heartbreakers to Slayer, and tons in between.
My personal favorite tape is my copy of Tears For Fears' Songs From The Big Chair, which was originally my father's, and one of the first albums I remember hearing any music from, along with Accept's Balls To The Wall and Twisted Sister's Stay Hungry.  I sadly don't have the latter two, though.

I own this demo cassette called "Malahrkee, Look Inside." It's from 1995 and it promoted a CD that probably never came out.
