YAY POP'N MUSIC
I play it a lot, on ps2 and arcade versions. Yup.
One of the funniest rhythm game I've ever played imo.
For info, I got pop'n 12 + 13 + any ps2 pop'n, actually (swapped PS2 :U), pop'n 16 and 18. I recently played pop'n 19 as well at a friend's, who has a real arcade machine, at his home. (epic week-end was epic :p)
