Steps for editing tags


I mean two Polish songs (I have on the disc):

Halina Frąckowiak - Serca gwiazd

time 3:16 (not in database)

Krzysztof Krawczyk - Pamiętam Ciebie z tamtych lat

time 4:11 (incorrectly as Halina Frąckowiak)

I am asking for a guide of editing or if there is too much explaining, could someone please edit this.
