A full album, also known as a long-playing record (LP), typically contains 10-15 tracks and can have a runtime of 40-70 minutes. It is a more comprehensive representation of an artist's work. A mini-album, also known as an extended play (EP), usually has 4-7 tracks and a shorter runtime, often 15-30 minutes. It is often used by artists to showcase a smaller selection of their work or explore a specific musical theme.
