wow this topic is going to go VERY downwhill.

ANything from beatmania is Good. :) 

High School Love sounds like it was MADE for DDR. I'm really surprised it hasn't shown up yet.

Blue Rain - dj TAKA vs. Ryu

Lovely Storm - L.E.D.

朱雀 - VANESSA (IIDX 14 Gold)

That song is SO sexy.

Vanessa will probably show up sometime or another.

I would personally like Dirty of Loudness. It fits perfect as a DDR Boss song.

One More Lovely...... as a boss song, rated at 15 blocks....

Anything by kors k.

I'd personally be happy with a return of Burning Heat! (3 Option Mix) from MAX2... or the IIDX 7th Full Option Mix cut.

Snapps: Dancemania License -

Hur hur, good reading.

...Kidding.  Actually, those were some pretty good choices.  I'd love to see more Wildside and CJ Crew in DDR.

Snapps' choices are pretty good. But I'm going to be an obsessive fanboy and point out that Secret Tale is from IIDX, but that Sana's version is better.
