How to delete songs that came with the iPhone 5?

I got a new Iphone 5 and it came with some songs already downloaded, i can't swipe and delete them, and i can't find them in my music library on iTunes

You can use a 3rd party software like this iPhone file manager, it can help you delete songs off your iPhone 5 easily.

Why, they are not even taking that much space and also just go to itunes and try to find them and just delete them there please Thank ya

Exactly
