Spotify has quietly updated its Mixed Playlists tools You can now fine-tune transitions smoother by amending effect curves It's starting to crop up for more users, and it's a smash hit so farThere’s one thing that Spotify does really well, and that’s offering a roster of different playlist-making tools for you to really get creative with. Though some are AI-powered, Spotify’s Mixed Playlists encourages you to use your originality when compiling songs, all while putting you in the DJ booth.Just as you’d get with music-mixing software, Spotify’s Mixed Playlists allow you to create smooth transitions between songs to ensure your playlist flows like a classic DJ set. Its mixing interface presents you with preset effects, and even tells you the key and BPM of each track — and now users have noticed a new upgrade that gives you even more freedom on the customization front. A recent post on the r/truespotify Reddit page shows the latest update, revealing that you can now amend the Volume, EQ, and Filter settings even more by simply dragging each effect curve to control how the transition runs. According to a small number of users, this feature has been live for a few months, but the majority of listeners in the replies are only now running into it — myself included. Spotify first launched Mixed Playlists in August 2025, hot on the heels of Apple’s own AutoMix function. But instead of relying on AI to mix songs, Spotify’s version puts the control right into your hands, and it quickly became one of my favorite new tools.

While these are still available, you can fine-tune your song-mixing even more, and after testing things out for myself I can see why listeners have taken to it so well. For starters, it allows you to clean up the small but noticeable imperfections in your transitions that you can’t achieve by presetting the three audio categories individually. For example, if you go into the Filter category and select the ‘High-pass filter out option’, it’s stuck in one place on the audio track. When you tap the ‘Customize’ button, three points appear on the effect curve which you can move around the audio track display so that your chosen effect comes in at a specific time.

When you start off with customizing your transitions, it can feel a little fiddly when trying to find the exact placement for each of the effect curve points but this you’ll get used to. Additionally, other users have also pointed out that the effect curve points sometimes move back to their original spots after you’ve shifted them. I’ve only run into this a few times, so it’s not a major issue that’s going to put you off for good. For once, it’s refreshing to see Spotify give one of its existing tools some TLC instead of pumping out new features without a lot of thought behind them. If this is the approach Spotify is taking from here on, just think of what it could do to improve features like this in the future.
