A compilation of songs assembled into a single sequence, usually encompassing many different artists and assembled by fans; often curated around a theme, mood, or personal taste; traditionally without legal permission. • A selection of songs recorded onto a cassette tape, often combining tracks by multiple artists, whether legally obtained or informally copied. • A playlist-style compilation of songs created on any medium (CD, digital file, streaming playlist), often shared among friends or online communities. • A digital compilation of music, whether created by an artist or a fan, that evokes the aesthetic, informality, or curatorial spirit of earlier physical mixtapes. • A musical project released under the designation; often characterized by looser artistic, commercial, or legal constraints than a formal studio album. • An independently assembled or distributed project, frequently featuring original tracks, freestyles, remixes, or performances over existing beats, historically circulated via cassettes or CDs. • A release by an established artist presented as informal, experimental, transitional, or promotional in nature, typically implying greater creative freedom, fewer industry expectations, and lower commercial stakes than an album. • A label-curated compilation designed to showcase multiple artists (especially emerging acts), often serving promotional or scene-building purposes.
