## JavaScript
```js
/* No JavaScript — a hidden checkbox is the transport: :has(:checked) flips play/pause glyphs and sets animation-play-state on the vinyl and EQ bars. */

/* No JavaScript — the active row is marked with aria-current and its mini-EQ runs on negative-delay desynced bars; hover states are pure transitions. */
```

How this works

Play state is a checkbox with the button as its label — CSS then runs or pauses every animation from one selector, the closest thing CSS has to global state:

.player:has(#play:checked) .vinyl{animation-play-state:running}
.player:has(#play:checked) .eq i{animation-play-state:running}
.vinyl{animation:spin 6s linear infinite paused}

The EQ is five bars scaling scaleY on offset delays (negative animation-delay desyncs them). The vinyl is the album photo with a conic-gradient groove overlay and a punched center via radial-gradient mask. The progress bar “plays” with a 210s linear width animation matched to the track length — decorative, honest about being CSS.

Make it yours

  • Track length = the width animation duration (210s here) — match your song.
  • EQ bar count: add <i> elements; delays stagger automatically via nth-child.
  • Swap the album art URL; the conic groove overlay adapts to any image.
  • Queue rows take a --art custom prop per row for the thumbnail.

Gotchas — read before shipping

  • animation-play-state only pauses — it doesn't reset; that's exactly right for a record player.
  • The play checkbox needs an aria-label that flips meaning via CSS content? No — keep TWO glyphs stacked and toggle opacity; the accessible name stays 'Play / pause'.
  • Spinning large images forever costs battery — pause by default, run on user intent (this demo starts paused).

Floor set by :has(), oklch(), backdrop-filter as this demo is written. The core technique itself goes back further — Chrome 105+.

:has() drives play/pause; without it the player renders paused (still beautiful). All animation is transform/opacity.
