Test Set

  • Harmonix Set (test split): 200 songs of the relabeled Harmonix Set (m-a-p/harmonixset_bigvgan, audio re-synthesized with BigVGAN), labels mapped to 7 classes (intro, verse, chorus, bridge, inst, outro, silence). These are the songs and audio of SongFormBench-HarmonixSet (identical files; annotations identical except for corrected endings of 2 songs).

For each metric, the best result is shown in bold.

Notes

  • Baseline SongFormer was also trained on SongFormDB, which may overlap with some popular song datasets to a small extent.
  • SCALE was trained on SheetSage-MSA, which may overlap with some popular song datasets to a small extent.
