Comet creates a Taylor Swift Spotify playlist

Sethi reports that Comet created and renamed a ten-song Taylor Swift Spotify playlist in six minutes, but selected from existing playlists rather than verifying streaming ranks.

OUR ADAPTATION

Suggested prompt

Suggested prompt written by Agents In Use, not the source author. Replace bracketed inputs and review tool permissions first.

Create a ten-song [artist] Spotify playlist. First show the selection method and evidence. If popularity data is unavailable, label it as a curated collection rather than a verified ranking, then ask before creating it.

What happened

Sethi reports that Comet created and renamed a ten-song Taylor Swift Spotify playlist in six minutes, but selected from existing playlists rather than verifying streaming ranks.

Reported by Monalisa Sethi

How the agent did it

  1. Specify the artist and number of songs for the Spotify collection.
  2. Have Comet inspect available song-selection evidence.
  3. Create the playlist and rename it in Spotify.

Where a person stepped in

Sethi inspected the selection method and identified its ranking limitation. The source does not document a separate approval gate or publish the track list.

Monalisa Sethi tests Comet on several everyday browser tasks during a week-long trial. The successful music task asks the agent to create a Spotify playlist containing Taylor Swift's all-time top ten songs. Comet builds the playlist and renames it, which gives the experiment a completed artifact inside the music service rather than just a suggested list in chat.

The important qualification is how it selected the tracks. Sethi observes that Comet scanned existing playlists containing Taylor Swift songs instead of checking stream counts. The resulting collection therefore satisfies the artist-and-playlist part of the request, while the all-time popularity claim remains unverified. The author reports six minutes for this run; it is a personal timing rather than a general performance benchmark.

The source does not disclose the ten track names, a public playlist link, the original account permissions or a separate approval step. This entry consequently does not invent them. The copyable detail is to distinguish the desired artifact from the selection rule: an artist-themed collection can be useful even when a ranking method fails, but a reader who needs the actual most-streamed tracks must check the ranking evidence. The suggested instruction below makes that distinction explicit before the agent edits Spotify.

Frequently asked questions

Was a playlist actually created?

The author says Comet created and renamed the Spotify playlist during the test.

Were these verified as the ten most-streamed songs?

No. Comet drew from existing playlists instead of checking stream counts, so the popularity ranking was not established.

Is the six-minute duration a benchmark?

It is the author’s timing for one run, not a measured guarantee across accounts and tasks.

Remaining steps

  1. Check whether the chosen tracks actually support the requested ranking.

About this account
