It's not the songs. It's the order.

Stop giving yourself whiplash

Whiplash happens when you go from a 128 BPM progressive banger straight into a 90 BPM lo-fi beat. Let's compare how TuneIt rearranges the exact same tracks into a smooth sonic transition.

Three steps.
Zero guesswork.

  1. Connect

    Sign in with Google and pick a YouTube Music playlist. Your sign-in lasts up to an hour, is never saved, and signing out revokes it straight away.

  2. Pick a mood

    Rise climbs. Drift stays calm. Unhinged throws curveballs. Frame plays out in three acts. Each track’s tempo and energy decide where it lands.

  3. Tweak & ship

    Drag any song where you want it, then save the new order straight to YouTube Music, or grab a CSV and move it anywhere with Soundiiz or TuneMyMusic.

No more whiplash

Your playlist already has good songs.
The order is the problem.

TuneIt reads the tempo and energy of every track, then reorders them so each transition makes sense. Pick one of four moods, and nudge any song by hand afterwards if you disagree with it.
