BEATLES has "Stran A:", "Stran B:", and "a hard days night" in the first few bytes, the ASCII characters are interspersed with NUL (0x00) ACK (0x06) and SOH (0x01) bytes.

Edit: it might be for a cassette inlay printing/catalogue software like the following (not _exactly_ this, though): https://www.jonessoft.co.uk/inlayprint.html

Edit2: maybe they are screen memory dumps from 0xB8000 with color bytes after character codes?
