I don't recommend Blooddrunk unless you're a 1 handed trill God and have enough stamina to the part afterward, FFLBF isn't too hard if you have endurance, same for Radio Heads if you can do left handed jacks, Big Blue is pretty tough overall, Scythe of 13 isn't bad if you have strong but well coordinated hands to hit the fast jumps that have the 16 thrown in, Epidermis isn't too hard besides the last 200 arrows or so in my opinion, I don't recommend FotBB unless you're a right handed runningmen and left handed trill king, you should probably wait on Erad until you can read fast jumpstreams and a bunch of chaotic patterns, Gymnastics is also hard unless you're good at jumpjacks and JS, BB Evo shouldn't be too hard if you have endurance but watch out for some fast streams and 8th jumps, Runnymoring if you're good at jacks and annoying trills, Demon Fire if you're good at JS with jacks in them and jumptrills, Lawn wake IV is also pretty easy once you can get down the fast streams, Club is

Club is mash unless you're a jacking God, Strangeprogram is pretty tricky because of the streams and 1 handed trills, 4 Chord has a pretty tough jumpstream that last a while with some fast 24th sections thrown it the middle, Mario minor is tough if you suck as much as I do at jacking with your right hand, AIM Anthem is obviously jacking, and EHHS is tough until you can do the 1 handed biased jumpstreams and the tricky parts at the beginning and end.

FGO songs: Go for Ketsarku or FN for now, and possibly Reality if you're good at streams and fast jumps. The rest of the songs are ridiculously hard, long, or both, so I don't recommend going for them yet.

Nice Demon Fire FC. You got it before I did <_<

FotBB should be a decent score FC.
