It's just that, when I'm in Japan I could foretell to a certain degree what would be accepted, so I certainly don't come up with any crazy arrangements.
Since I was doing all of it myself, I had to decide where I wanted to go with the songs, how to proceed with the chords, if the sound was alright, and all that detail on my own.
The Japanese version comes with a translation, but that's different from the lyrics, so people could look things up and find a translation of their own if they're interested.
