Two maswali about Victoria in Spectacular!?

I know that this is a "simply" question, but ¿of wich musical genres are the songs that Victoria are in? I'm want konw that genre cause I upendo that!
Oh, and another thing! is true that Victoria are in "Eye Of The Tiger" and "Everything Can Change"? Because I see that affirmation on various pages, but I never found it on these songs? I'm so confused? They too give credits to Simon Curtis on these songs...
