Doubt: Double Stage HPSS calculated over first P component about ismir2018-revisiting-svd HOT 1 OPEN

Hi,
if you check paper from Leglaive et al. which is referenced in readme.md, you will see that they mention that singing voice is considered to be in between percussive and harmonic components. I think it makes sense since pronouncing consonants, for instance, are more percussive than harmonic. Also, singing style varies so it is hard to assume that double harmonic components will capture all the singing styles.
But if you are not reproducing the paper, you are always free to experiment with different methods. :)
