What are some positive, optimistic and cheerful songs? Personally, I think there are actually many such songs. For older songs, you can listen to Beyond. Most of their songs can actually make people regain their confidence quickly. I personally think these are great songs to listen to when you're feeling down. There is also a song called I Believe sung by Yang Anpei. I personally feel that listening to this song will arouse your fighting spirit when you are feeling down or have no confidence. There are also animations like "Slam Dunk", the ending and opening songs are very good. It can make people's blood boil and their fighting spirit high. In fact, a lot of fast-paced and exciting music can make people feel optimistic and cheerful.
