Grooves, or tracks, refer to the physical indentations found on vinyl records that store audio information. These grooves spiral from the outer edge to the center of the record, allowing a needle to read the vibrations and convert them into sound. Each groove represents a different sound wave, capturing music or spoken word in a tangible format. In the context of digital music, tracks are individual pieces of audio that can be played, downloaded, or streamed. They are often part of a larger collection, such as an album, and can be categorized by genre, artist, or length. Vinyl records, digital music, and albums are all related concepts in the world of audio.
