Nuh uh, Castle Siege and Port Town have the best tracks.
Also, I just got my game back today and after a brief scare of unreadable disc, I've been slowly unlocking all the characters. I also heard the Metroid music for the first time and honestly, the narration is so quiet I could barely hear it. Don't see why others would be so bothered by it. Ice Climbers also has it, but it's harder to understand what she's saying. The song itself is good, but inferior to the Brinstar remix.
Also, Weegee is even more hilarious than his past selves.
