speaking of which, it's a pain in the ass when you can pull the XA audio from a PS1 game, but that's just cutscene stuff, and you can't find the PSF data.
It's a pain manipulating audio to sound different while retaining it's original sound, it's a pain to rip music from an audio file with voices talking or singing in the background. It's a pain to loop songs without knowing the loop points, it's a pain...well you get my point lol.
