I just had to say this since I havent heard it anywhere else (maybe I suck at searching tho..). The pausemusic from Battletoads (NES) plays during some of the loadscreens in Banjo Kazooie: Nuts & Bolts. I picked up a copy of this game today and one of the first things I noticed was this particular piece of music playing during my first loading with the Gamemasters face covering the screen. Maybe I´m just way to old school but I´m pretty sure its intentional since Battletoads is an old Rare Ltd. classic. Anyways, let me organize it for you so that those of you not yet aware of this awesome omage can share the joy ! Now its appearantly super hard to find even one clip where they show an actual loading screen so you have to crank up the volume on the clip I found. Its already very subtle even on a home theatre setup so listen closely on the loading screen.
Also, on a sidenote, did you know that a track from Donkey Kong Country 3 is actually called "Nuts & Bolts" ?
