Honestly, I wasn't expecting the soundtrack to be all that great, but I actually like it. There's 50 songs total(including unlocks), and there are two 10 footers. Compared to the difficulty to Mario Mix, I was surprised to see any 10 footers on a Nintendo DDR game. There's also a decent amount of 9 footers as well.
So yeah, if there's any way to get a good pad to be used with the GC port(Answer to Penfold's question) in the near future, it's definitely worth looking into.
I've uploaded a handful of videos from the game on my YouTube account if you want to check those out.
