TUNEBAD

Playlist key & BPM analyzer

Paste a public Spotify or YouTube playlist link. TuneBad matches every track against its 2,500+ song community database first, then analyzes anything missing right in your browser with the same essentia engine as the Key & BPM Finder. No uploads, no signup.

Works with public Spotify and YouTube playlists, up to 100 tracks.

How it works

Spotify and YouTube do not publish key or BPM data, so TuneBad matches each track to its official 30-second preview and runs the same key/BPM detection used across the site. Songs already analyzed by someone else show up instantly from the shared database; everything else is analyzed on the spot and added to it, so the database gets more complete with every playlist pasted here.
