Speed Up or Slow Down Spotify Playback While doing math homework

💡 Overview

Spoken content rarely suits normal speed. A worksheet and a calculator are open next to a music tab.

Playback rate runs from 0.5x to 2.0x, with presets at 1.0x, 1.25x, 1.5x and 2.0x. The extension locks the rate so it persists as tracks change, rather than snapping back to normal every time a new item starts. That matters for podcasts and audiobooks, and can be fun for slowing music down to learn a part.

🧭 A Day of High School Students

A worksheet and a calculator are open next to a music tab.

The problem: One click on the music tab often turns into video scrolling.

The fix: Never open the tab; use the popup, a hotkey and nothing else.

🚀 Try It in Three Steps

1. Open the popup and pick a speed preset.
2. Choose 1.25x or 1.5x for podcasts, or 0.5x to study a passage slowly.
3. Return to 1.0x with one tap when you want normal speed.

✨ What You Get

• Floating mini-player: Popup with play, pause, next, previous, shuffle, repeat, seek and a Liked Songs toggle.
• Zero-polling design: A MutationObserver updates the UI only when the page changes, keeping CPU and memory use low.
• Playback speed 0.5x to 2.0x: Presets at 1.0x, 1.25x, 1.5x and 2.0x, locked across track changes.

Note: it works with the Spotify Web Player at open.spotify.com only, and does not control the desktop app.
