I'll explain why I like each one
1st) The first one because it's very deep and cool. The struggle between two sides and which one he should go with.
"Either destroy myself or destroy everything else" and "For the sake of justice destroy, all evil right now" are two very badass lines innit
2nd) The second is just a fun bop song about dancing to you're heart's instincts. But I feel like someone told me it had a darker meaning and it was the ED for the edgiest saga in the series Black Saga so idk. I think it's just cheery.
3rd) The third one is a self-reflectional song about how far you've come along from being a little boy but also is a generational song about the son family? I find it as a nice, positive and self-affirming song about one's journey to the end. Being a kid to raising a kid. (Also goten should never grow up, We need cuteku to stay in the franchise)
