Crepuscolo sul mare (Piero Umiliani)

Our rubato finder is perfect for the first 1:39: all 40 of your marks, no extra cuts.
After that it slips (20 of 25, 5 extra). There Beat This!, the AI judge and MERT do better in Solos 4 and 5.

The World We Knew (Herbert Rehbein)

Beat This!, Apple's model, Fusion and the AI judge hit 39 of your 40 marks. The one miss is at 1:25.
Our rubato finder is perfect in the verses and Solos 2-3, but loses the bar in Solo 1 (1 of 4) and the intro.

Tu vuo' fa' l'americano

Beat This! (Fusion picked the same cuts) hits 99 of your 100 marks from 0:45 to 3:00.
At the start and the last 30 s it fails: you held shots longer there, and it keeps cutting every bar (34 extra cuts).

Endeavour (Algonquin)

In the four beat parts, Beat This! and Final Cut's Beat Detection hit all 34 of your marks, with no extras.
In the slow parts both fail: they keep ticking (14-21 extra cuts) where you held long shots.
