I saw this on DR Wiki and was confused, since Metal Crusher shows up in three tracks. I realized it was talking about how that beginning part is the melody only present in a single track, since those three tracks use 0:20-0:37 as the Metal Crusher motif... but even that isn't right. The unlisted track grandpa_temi uses the beginning part of Metal Crusher, mike_reset from Deltarune is actually that song just ripped from UT.
So it seems false, doesn't it? Metal Crusher's motif should be in two parts, with grandpa_temi being the sole other song to reference part 1 in Undertale.
