1. Pick a winner in every matchup. Tap the song you like better. Do that through all four regions — the four regions — and each region crowns a winner.

2. Then hit the Finals tab to crown your champion. Your four region winners meet there — pick your way through the Final Four and the final, and lock in the one song that wins it all. That's the finish line.

3. Don't know a song? Hit ▶ on any song for a quick preview — or on a phone, press & hold any song (works in every round). Great for jogging your memory or comparing two you don't know.

4. Want a head start? Tap Auto-Fill up top to fill the whole bracket instantly, then change any pick you disagree with.
