Ratchet and clank 2 glitches

Answer 1

I just was playing the game, trying to get enough bolts for RYNO 2 when I was exploring Planet Oozla (the first planet) and I found this totally random glitch! What you need to do is complete the level for the first time, then go to another world, then come back. Now, from the start of the level, go the way you would to get inside the Megatron Market. Once you've beaten that, go back to the start. Now, go the other way with all the weird animals in the water. Die in the water. Now, the music should be the music in the Megatron Market.

Note - If this doesn't work, I'm sorry. If this is not how you complete they glitch but you know how to, please post instead of mine.

I did not cheat or hack the system, if that is even possible...
