It's Captain Jack/Only you from DDR 4th mix soundtrack.
I've been listening to the two soundtracks that I have almost constantly (4th and 5th mix)
Though relief is on the way. I bought some cds off ebay for 20 bucks.
Beatmania 2nd, 3rd, 4th, 5th, and maybe 6th mix
so another 4 hours of bemania songs all with a megamix disk. :)
woohoo now if they only get here.
