Does anyone remember Aristocarts? They were blue and I think they were made in Canada. The frequency response seemed to be excellent when I worked at a station that used them for most of our music, but the tape was very fragile. We would usually have about a half dozen eaten on the air per week, and sometimes more than one per day. When I was on a quick weekend trip in the next state and I was listening in the car for our sister station in the next market, I wasn't sure it was them I had just tuned in on the fringe of the signal until I heard the song end abruptly in a garbled mess when the cart was eaten on the air.
