I'm really pushing the limit on how many voices one person can play on the piano. I was already pushing it with Omoide Shiritori and Connecting, and that turned out way better than I expected. Plus, I also really like songs with a bunch of key changes, like Touhou (definitely not foreshadowing :P) or medleys (this is also not foreshadowing XD). I also had a really strong 'transcribers' block' on the newer anime season songs, and I much prefer to learn Animenz's or zzz's transcriptions than making my own, but who knows hehe :P
