Two songs play head-to-head. Tap a side to hear it, then swipe up or down to cast your vote — by default, swipe toward the song you’re choosing (you can flip the direction in Profile → Swipe to vote). Your vote updates each song’s global ranking.
No. DeuxDuel plays 30-second previews available to everyone. An Apple Music subscription only adds the option to save full songs to your library.
A category only publishes a public ranking once enough distinct people have voted in it, and a song only appears once it has enough appearances of its own. This is deliberate — it stops a chart claiming an order that a handful of votes can’t support. See how the ranking works for the full explanation.
Matchups are drawn from the category you’re in, not from your listening history — that’s what keeps the chart from turning into a personalised feed. Use Browse to pick an era or genre you actually care about, and the pool narrows to it.
Not today. DeuxDuel is iPhone-only and requires iOS 17 or later.
The one matchup we feature for you each day on Browse, tuned to your taste profile and, over time, your voting history. Prefer to play on your own schedule? The Throwbacks shelf on Browse has other Sets any time.
Profile → Your Badges tracks the artists and categories you’re closest to completing, and the ones you’ve fully completed — meaning you’ve judged every song credited to that artist, or every battle in that category.
A custom head-to-head you build yourself and share with friends. Pick songs, name it, choose a format, and send the link.
Bracket is knockout rounds down to one winner. Smart Rank produces a full ranking in as few picks as possible. Vote All pits every song against every other song for the most complete picture.
Vote through pairs from a themed lineup (find them in Browse → Arena & Events). Your own ranking locks in as soon as you finish; the combined ranking from everyone’s votes unlocks once the Event closes.

Open the paywall and tap “Restore Purchases”.
Tap “Restore Purchases” on the paywall first — that re-syncs your entitlement with Apple. If ads persist after a restart, email support@cb-industries.co with the Apple Account you purchased under and we’ll sort it.
In the app, go to Profile → Delete Account and confirm. This permanently removes your account and all associated data (votes, history, and profile) right away. You can also email support@cb-industries.co from the device’s Apple sign-in and we’ll delete your account and associated data within 30 days.
The short version: your votes, your account identifier, and anonymous usage analytics. The full detail is in the privacy policy.
