Your Lies [48 or 54]
 

It's 2 1/2 minutes of snorefest, but then have broken 16th note jumpstream with hands thrown in. All the difficulty is crammed into about 30 seconds, but it's still a long song. I'd say the BPM on the broken jumpstream with occasional hands part is about 132 bpm (not measured, just guessing), and is not like anything else seen in the 40s. It feels much more in line to find its home in the 50's somewhere.
