If the play back head on the deck was out of alignment you could hear the other tracks playing between songs, faintly. Some times you could hear the other tracks backwards. Honestly, 8tracks were terrible. Cassettes were so much better, then CDs. What’s sad is that we still have to use CDs for lossless content. Discs have been around for over 30 years and still...lossless content is more or less boutique.
