# deckard posts "Claude-Pop - I'm Upping My P(Doom)", a Suno remake of a 2024 AI-doom song, on X

On 2026-09-09 X user deckard (@slimer48484) posted a 2:37 Suno-generated "Claude-Pop" rendition of osmarks' 2024 Udio song "P(doom)", whose lyrics are dense with AI-safety in-jokes. It went viral in AI circles (~723k views, 2.5k likes). Two weeks later its audio track became the soundtrack of the Opus 5.5 music-video wave ("Claude Pop").

## Key facts
- X post 2026-09-09 18:22 UTC; video 156.6 s, 1920×1080; ~723k views, 2,537 likes, 229 reposts, 126 replies (fxtwitter, 2026-09-29)
- Audio made with Suno (per mexicat's README and Pratham's credits); osmarks' page calls it 'Claude-Pop version from alternate Suno song variant'
- Lyrics: MusicPerson (Apr 2024) + osmarks (2024-04-17 and 2024-11-08/09) + EleutherAI Discord suggestions + a Claude model (outro/final chorus)
- Why 'Claude-Pop' was chosen as the style name is not documented. deckard had earlier shared Anthropic's 'Claude FM' stream (May 2026). Low confidence on any connection

## What happened

deckard posted the track with just its title. Reactions focused on how catchy it was and how many references it packs in. Laura Heacock (2026-09-10): "you can catch up to about 2 years of X posts if you simply go through this line by line". Re-uploads appeared on YouTube (Jacob Valdez on 2026-09-11, Drought Bee on 2026-09-18) and a Suno cover followed (2026-09-13, animated by GPT-6 Astra agents).

## Why it matters

It supplied the audio and the name for the "Claude Pop" genre. Suno v6 launched the same day, but deckard does not say which Suno model was used.
