I agree, but it is what it is. I've accepted it.
EDIT: On a side note, want proof that Sakurai and company didn't give a rip about Prime or Pikmin? The song choices heavily suggest this. Take a look:
Most of the Metroid Prime songs included were from the Menu/Screen selection. The only song that wasn't was Parasite Queen, which is a pretty worthless battle choice. So, why choose it? It was one of the first levels you encounter in Prime 1, within the first 10 minutes of the game. I guess you could count the Meta Ridley battle, too, but that was basically another remix of the other Ridley boss battle music.
For Pikmin, there are hardly any song selections from the actual game. Three of them are random songs from the commercials. Two more were, again, just the menu/selection screen song. One was the end of day song remixed, and another was just random environmental noises. Again, the only exception to this was the Forest of Hope...the first stage you encounter in Pikmin 1.
