16gb or 32gb iPhone 5?

I'm probably going to get the iPhone 5 next month and I want to know which one would be better for me. And for for some background info, I'm a teenage girl.
So, in my iTunes right now, I have 2.49 GB worth of songs, but of course my music will grow. I want to put that all into my phone.
I also will probably take a bunch of photos (I guess I can delete a lot as I go) but no videos.
I want a lot of applications such as: around 3-4 games, social networking sites (Facebook, Facebook Messenger, Twitter, Instagram, Tumblr, Snapchat), Pandora, around 8 picture-editing/picture-taking apps, Shazam, Yelp, note-taking app, and a few more apps here and there.

But yeah, that's basically it. Apps, music, and photos I believe. Which do you think will be better for me? (if you don't take in the price) Thanks!!
