Oh yeah, hurry through the unexplored land

So I was just playing Sonic Adventure 2: Battle on the GameCube and I thought I'd do this little fun (read: useless) project. Basically, I'm going to attempt, using a combination of a katakana table and Google translate, to write the level names as they would be written in Japanese katakana (the Japanese system for writing non-Japanese words), transliterated back to English letters. As an added bonus (since I really like them), I'll add the names for the music tracks that play during those levels. Are you ready? Okay, let's go!

That's it! Keep in mind these are my own approximations, the actual game might write some of them slightly differently. There is no "one" way to write foreign words in katakana, since the whole point of katakana is meant to approximate the sounds of non-Japanese language. For instance, the word "angel" is often written as "Enjeru" in katakana, but I've also seen it written as "Enjuru".
