Fairly basic question, but I'm having some troubles with the genitive case? For example, would さかなのボール be the fish's bowl or the bowl's fish? I've always assumed it was the first order, yet a few things I've seen recently seem to contradict that　like Uta no Prince. Song's Prince wouldn't make much sense.
