Spotify is obsessed with the idea that somehow, someday, it will be able to always put on the perfect song every time you hit play. It’s turned playlist-making into both art and science, and its auto-generated Discover Weekly playlist has become the service’s best feature. In its long quest to soundtrack your life with sick beats, it’s even started working with producers and DJs to make original tracks. And now Spotify wants to help you party. To be there when you’re finished throwing back three more Jager Bombs, ready to help you fist-pump the night away.

Spotify Party is mostly playlists. Some are just general party music, curated by Spotify as usual. The more impressive set are the playlists filled with beat-matched music, so you never get that awkward thing where one song ends, another begins, and suddenly your bad self is getting down to the wrong beat. Beat-matching is DJ 101, but Spotify’s doing it for you now.

There are playlists for lots of moods and party types, from the glass-shattering banger to the glass-clinking cocktail soiree. (Those aren’t the names, but you get the idea.) With the Mood Tuner, you can even ratchet the pace of the party up over the course of the night, making sure you’re in full swing at the right time. Turn it to “Start it up” when people are rolling in the door, switch to “Hold it down” when the champagne starts pouring, and flip to “Set it off” when it’s blackout-o-clock. You pick the level of the party, Spotify gets it there.

Spotify’s also continuing its dive into original EDM production by partnering with Diplo to create more than 120 original tracks. Like Tiesto’s running tunes, the music is designed to be sped up and slowed down to suit your mood.

Everyone knows a bad song can kill a party. (And that “Hey Ya” can save it.) Spotify’s betting that its algorithms can make sure the beats keep coming, and coming, until long after you’ve given up and gone to bed. To be fair, you could always just put “Party in the USA” on repeat all night, but Spotify’s way is a lot more high-tech.
