I'm aware of the fact that you might not know Konstantin Gropper since he is a German singer sonwriter (his band is Get Well Soon)..... I saw him live for the first time yesterday, and really wondered what his personality type might be...since...as far as his lyrics go and what he said in between his songs I thought he might be an NF, most likely an INF, and maybe even INFJ.... however, I'd say I for sure, but he could also be NT..... I know that there is not much availabe in English on him.....but I'd really like to know what you think about his type.......
