Cassette tapes, the dominant music format before CDs and streaming, are generally expected to last around 30 years even under ideal conditions, since their magnetic coating gradually loses lubrication and can detach over time. However, actual longevity depends heavily on how tapes were stored, with many well-kept cassettes from the 1970s and 80s still playable today.
