WildSongBench results and evaluation scope
The reported results describe generation with symbolic planning under the recorded automatic-evaluation protocols. They support frontier quality: YuE2 is competitive with Suno v5/v6. They do not establish universal metric superiority or human preference.
The interactive demo results, full WSB results CSV, and WildSongBench dataset provide the public result and benchmark resources.

SongBench Avg is the mean of seven dimensions. SongEval Avg is the mean of five dimensions from a separate automatic quality evaluator. SB Musicality and SE Musicality report the respective musicality dimensions. AudioBox PQ measures production quality; MuLan and AllMusicCaps assess text/audio alignment; prompt control uses Q3O on a 0–5 scale. PER is phoneme error rate, for which lower is better.
Candidate selection. Standard YuE2 selects the lower-PER candidate from two generations. Best-of-8 selects by SongBench Musicality, then prompt control, then PER. Each candidate's PER uses the lowest PER from four ASR passes. This selection uses a SongBench dimension and is not equivalent to one unselected pipeline call. Prompt-control weights differ on 10 of 192 prompts between the two selected YuE2 settings.
Public baselines, Suno v6, and Suno v6 Wild use two candidates and four ASR passes per candidate, followed by lower-PER selection; earlier proprietary systems retain their delivered-candidate protocols. MiniMax Music 3 uses its official caption rewriter and is classified as a public model because its weights are released and the evaluated campaign uses them locally. SongBloom uses a fixed audio prompt. These are documented system comparisons, not matched-compute experiments.
Both YuE2 settings use melody-and-chord planning and the verified evaluation decoder distributed as YuE2-Vae-legacy. Default listening uses YuE2-Vae. Keep their audio separate; use the same cached acoustic latents for decoder comparisons. The release names determine these roles, not the everyday meaning of “legacy.”
What the lead means. YuE2 (best-of-8) has the highest observed SongBench Avg, 6.9632; the highest proprietary mean is Mureka 9 at 6.9377, while Suno v5 scores 6.8721, Suno v6 scores 6.5562, and Suno v6 Wild scores 6.4195. The small gaps are descriptive, not claims of statistical significance. Different systems lead other metrics: Suno v6 has higher SongEval scores than both YuE2 settings, and both v6 variants have lower PER and higher AllMusicCaps scores. The unqualified YuE2 setting scores 6.7316 and is already within the proprietary quality range.
The overview figure combines SongBench and SongEval into a normalized song-quality index and MuLan, AllMusicCaps, and prompt control into a normalized text-alignment index. These axes are comparison indices, not percentages of correct output. Bubble area indicates AudioBox PQ; outlined points are Pareto-optimal on the two plotted axes. The 15 external baselines define the z-score reference; quality weights SongBench Avg and SongEval Avg at 2:1, while alignment weights its three metrics equally. Each axis maps the observed extrema across all 17 settings to 10 and 90. Figure data and normalization · Full-precision CSV · JSON.
