LPs are often associated with classic rock, jazz, and other genres of music, and are cherished by collectors. Synonyms for longplaying records include vinyl records, phonograph records, gramophone records, and LPs. Each of these terms refer to the same format, but "vinyl records" specifically refers to the material used to make the records.
