Ripping PS2 music

After playing the PS2 Chou Aniki game, i've decided i need to rip that beautiful musical masterpiece. However, after some googling, i did not manage to find anything able to do the task.

Anyone knows how it can be done?

Play the music and record it with windows sound recorder, the result will be in .wav so you wont need to convert it anymore.....however unwanted anomalies likes sound of a car passing your house, may get recorded as well.
