A long time ago, when I first discovered Sound Test $10, I'd only ever seen the screen shot of a desert zone, supposedly cut from Sonic 2. I'd never heard of (or seen any shots of) Hidden Palace at the time. Naturally, I assumed it was the theme to the cut zone. Now, years later, after having heard of Hidden Palace, everywhere I turn I hear Sound Test $10 referred to as Hidden Palace. Yet, in the Beta, this is not the music applied to that zone. I know this might be placeholder music (like Starlight Zone's BGM in the Alpha), but Masa has said in <a href="http://info.sonicretro.org/Masato_Nakamura_interview_by_Sonic_Central_(May_18,_2005)" target="_blank">this interview</a> that he composed music specifically for the zones, after seeing art for them. Now, Sonic 2 may have different, what with the added headache of having to keep in contact between the STI in Palo Alto, and Masa's studio in London. The question is, what absolute, ironclad, unassailable proof do we have that Sound Test $10 was intended for Hidden Palace Zone? If there is none, what is the best evidence? No "I think it sounds more like a palace level", please, because I've always thought it sounded like a baking desert, because I heard in it what I expected it to be. These things are very subjective. The reason I ask is because I'm putting both zones in my game. I don't know whether to go with my opinion (Sound Test $10 sounds more like the desert zone), with majority opinion (Sound Test $10 is Hidden Palace), or if there is some way to objectively clench it either way.
