Music tapes, commonly known as cassette tapes, are a type of analog audio storage medium that became popular in the 1970s and 1980s. They consist of a magnetic tape housed in a plastic casing, allowing users to record and play back music. Cassette tapes can hold up to 90 minutes of audio and are played using a cassette player. These tapes were widely used for personal music collections and mixtapes, enabling people to create custom playlists. Although digital formats like MP3s and streaming services have largely replaced them, cassette tapes have seen a resurgence among collectors and enthusiasts who appreciate their nostalgic value.
