There is a typo.
しります works as the future tense.
Do not use sentence final particles. It's incredibly hard to use them correctly even for fluent learners, and incorrect use of them sound rather unnatural.
ちょうど is not appropriate as the translation of "just" there.
みせた doesn't make sense since it means "my father fascinates Opera."
思います works as the future tense.
There is a typo in さねん.
Again, do not use sentence final particles.
A period should be put after the first sentence.
の is the pronoun in ゴリラズの, thus, it means "Gorillaz's one(s)/song(s)". "My favorite band is Gorillaz's song(s)" doesn't make sense, right?
聞いてみます shows that you haven't heard their song yet.
この doesn't mean "their song(s)" there.
