AI Music Deduplicated

A large-scale collection of AI-generated music from five platforms: Mureka, Riffusion, Sonauto, Suno, and Udio. Each song includes the original audio file and its full platform metadata as a JSON sidecar.

Overview

Subset	Songs	Tar Files	Size	Audio Format	Source Platform
mureka	~312K	49	~981 GB	.mp3	Mureka
riffusion	~105K	14	~266 GB	.m4a	Riffusion
sonauto	~15K	2	~25 GB	.ogg	Sonauto
suno	~307K	65	~1.3 TB	.mp3	Suno
udio	~126K	33	~642 GB	.mp3	Udio
Total	~865K	163	~3.2 TB

Dataset Format

This dataset uses the WebDataset format. Each tar file contains pairs of files sharing the same numeric key:

00000000.mp3      # audio file
00000000.json     # metadata JSON
00000001.mp3
00000001.json
...

Tar files are capped at ~21 GB each. The directory structure is:

mureka/
    mureka_000000.tar
    mureka_000001.tar
    ...
riffusion/
    riffusion_000000.tar
    ...
sonauto/
    sonauto_000000.tar
    sonauto_000001.tar
suno/
    suno_000000.tar
    ...
udio/
    udio_000000.tar
    ...

Loading with WebDataset

import webdataset as wds

dataset = wds.WebDataset("mureka/mureka_000000.tar")
for sample in dataset:
    audio_bytes = sample[".mp3"]          # raw audio bytes
    metadata = json.loads(sample[".json"]) # parsed metadata dict
