Would be cool if they still have music like this

That's a big mistake, especially since you don't have the soundtrack creating the mood.

While it seems that the events in Apollo Justice will be important to this one, I suggest just reading a synopsis or something.

It'd be criminal to skip Trials and Tribulations, though.

I seriously need to play Apollo Justice...

I can see why you can say these things. It's obvious you've never played an AA game before

Trust me. Reading the story will ruin part of the fun. But also, by not listening to the music, you'll miss one of the most goosebump-y scenes in videogame history

I don't think it will affect your enjoyment of DD much, although I will say that playing the older games is a much different experience than reading their scripts. That said, if you're just going for DD, you should be fine. You'll probably miss a few inside jokes from the older games in the series here and there, but it shouldn't be anything massive.

The music for Ace Attorney is utterly fantastic, though. It's probably worth looking up on youtube just to listen to even if you're not setting the mood for anything.

Edit: nevermind.
