Music in English and Japanese

Occasionally I would encounter some good music in English and Japanese, and it would bring me so much satisfaction, such as:

Along with the improvement of my English, the songs once I collected were not the type I still enjoy, and now, it’s not hard for me to fully understand an English song, also it means it’s not that a challenge to me to collect English songs, therefore maybe Japanese songs are a good choice for me

1. The quantity is huge
2. The music is good
3. The culture is I like, such as 物の哀れ
4. I am still willing to learn Japanese, though I know it’s super difficult

English is for freedom, then Japanese is for what?
