No big deal, I was just curions about the process.

I didn't know about '-P_', I normally use a range, such as '-P 1..3' or
just '-P 10'. And, very interestingly, there is a difference:

b4 shazam -P_ 20260723131649.134127-11-panchuang@xxxxxxxx -> does not take the R-by from the cover
b4 shazam -P10 20260723131649.134127-11-panchuang@xxxxxxxx -> takes the R-by from the cover

So, looks like '-P <num>' is the answer. :)
