U-Prince: The Crazy Artist (2017)

Similars

One simple aspect music and musician and student. In the Hippie is a student too, but hey. There is great music in both and the lead actor in both composed the music and wrote the songs and sung them and performed them. So it's just fitting that it's here. However, Hippie is far from a liar. He's ridiculously raw and straightforward. This is on the superficial level of just music and rock.
One of the best bittersweet movies I've seen. The premise is fairly the same of an artist (of a different genre) with a neurological condition meeting a young female student. In both stories the characters learn more about themselves and the true meaning of love and life.
