What songs are you stuck on?

[lmmortal]

I just can't increase my rank on either CIA Rave or Crystalis. The part in CIA Rave that I can't get past in the part with all the jumps, and part in Crystalis that is holding me back in the 666 then 46 jack. Those are the only two songs that I have above rank 3k now, and then I have like 9 or so songs above 2k rank that I just need to improve my PA on to get below 2k.

I've played both CIA Rave and Crystalis so much in the past couple days. Really tired of those two songs.
