Well what can I say ... at some point in my life, music became something I couldn't go a day without. Now, I don't really listen to classical music but I have a huge appreciation to the people who created all those masterpieces. In this anime, we can hear A LOT of different classical music pieces that suit incredibly well in the scenes they are played at!
I love how many scenes, just as "Titan's finale", Lenny starts playing 4th/Final movement of the 1st symphony of Gustav Mahler - which funnily enough, this symphony has the nickname "Titan" - how cool is that?
Obviously there are a lot of other interesting musical moments throughout the show, which will take a long while for ma to list, but what I can say is that, Takt Op. Destiny is one unique anime that contain a little bit of everything with the biggest impact being - music. I am sure people who have a high appreciation of art and music will also enjoy this!
Without including any spoilers. all I will say is - give this anime a shot since you might very well end up surprised from what it has to offer!
