Ad Blocker for Spotify Web
This is an experimental, simple chrome extension to remove audio ads on Spotify web player. It's available on the Chrome Web Store too.
How ads are removed
Ads are removed by intercepting and then tampering with Spotify's state machine requests/updates on the fly.
The states are modified so that states that represent ads are skipped over (pointing to the state afterwards). This is done in ads_removal.js.
