Grummy

An adjective denoting the already waxy, slightly washed out sound of a brand new vinyl record you just barely opened to play. Most often seen in vinyls bought from supermarkets and similar large chain stores for high prices after the resurgence of vinyl records into the mainstream. Note that this word doesn't apply to old, well loved vinyls. Your grandma's Stones album from college that sounds like it's being played through a wall in present day is well worn. Grummy vinyls already had poor sound quality at manufacture. Generally not a problem if you're not a total audio freak, but those concerned with sound quality find grumminess quite annoying.
